Muhammad ibn Qasim: The 17-year-old General Who Brought Islam to South Asia

بسم الله الرحمن الرحيم

In the Name of Allah, the Most Gracious the Most Merciful

Muhammad ibn Qasim  رَحِمَهُ ٱللَّٰهُ was a legendary youth commander who helped spread Islam into the Indian subcontinent. Following the footsteps of Usama ibn Zayd  رضي الله عنه  in age and military leadership, he represented the best of youth in service to Islam. In only three years he conquered Sindh and spread justice in a far land. From conquests to diplomacy, this article examines Muhammad ibn Qasim’s political legacy.

The History of Sindh

Sindh’s lands extends to the Himalayan mountains and is today much of modern Pakistan. The conquests into this region originally began under Muawiyah ibn Abu Sufyan, however the entire area didn’t fall to the Muslims until the caliphate of Walid ibn Abdul Malik.

Before Islam's rise, the region of Mekran (in which Sindh was to the east) was part of the Sassanid empire. This was until the armies of Umar ibn Al Khatab  رضي الله عنه entered the region and Mekran passed into Muslim hands. Caliph Umar forbade any further conquests into Sindh in order to live at peace with their neighbours. The Muslims remained friendly with the Raja of Sindh, however they were hostile in return. Soon the region became a haven for opponents to the Islamic regime, whose ships often waged attacks on the Muslims.

In 85AH, Raja Dahir became the last Hindu king of the Brahmin dynasty of Sindh, then a territory of India. He ruled parts of modern day Afghanistan, Balochistan, Pakistan, and Iran. Dahir was hostile to the Muslims. He’d helped fund a rebel's uprising in Mekran which was put down by its Muslim governor, who didn't punish the Raja.

However, when Hajjaj ibn Yusuf came to power in Iraq, he was a tough ruler who punished his opponents severely. When he heard of Mekran's riots, he sent a deputy to crush the rebels who sought refuge with Dahir. The Hindu Raja was extremely kind to the rebels, expressing open hostility to the Muslims. The lack of response made Raja Dahir believe he was too powerful to be challenged. However, an international incident triggered the Muslims to finally conquer the region. (Akhtari, 2015, 6)

The Call of the Muslim Captives

Since the time of Muawiyah ibn Abu Sufyan, the Muslims had become skilled sailors and the Arabs maintained dominance over the sea, travelling between the Indian Ocean and other seas for trade.

In 88 AH, Arab ships set sail from Ceylon in which women and children were aboard, travelling for Hajj (pilgrimage). Each year when pilgrims travelled to Makkah, the Raja of Ceylon sent gifts for the caliph. That year, the ships carried gifts for Caliph Al-Walid ibn Malik.

On the way to Basra, the ships were attacked by a storm on the coast of Sindh, which caused them to land in Debul, east of present-day Karachi. Pirates operating in the area plundered the ships. They looted the wealth, killing the men and kidnapping the women and children. However, a few surviving men escaped to Basra. They told Iraq’s Governor Hajjaj ibn Yusuf what happened, who raised the matter with Raja Dahir. 

Al-Hajjaj sent a letter demanding the captives' release and the pirates were punished. Dahirrefused, which insulted the governor further. He wrote a letter to Caliph Al Walid, asking for permission to invade Sindh. (Akhtari, 2015, 7)

Unsuccessful expeditions and Appointment of Muhammad ibn Qasm

The first Arab expedition into Sindh was led by Ubayd Allāh ibn ʿAbd Allāh who passed through Mekran into Sindh. Dahir sent an army to attack the Arab force which destroyed much of the Muslim army and martyred Ubaidullah.

Al-Hajjaj sent another expedition under ʿAbd al-Raḥmān ibn Budail, this time the Arabs prepared a bigger army. However, the Hindu army commanded elephants, which frightened the Arab forces, leading to the defeat of the Muslim army and Budail's death. 

The two failed expeditions didn't deter Al-Hajjaj who sought the caliph's permission to retaliate. Al Walid agreed and Hajjaj carefully planned the next outing, determined to be successful. He appointed his young nephew Muhammad ibn Al Qasim Al Thaqafi who was the governor of Shiraz. Muhammad was 17 years old but a capable governor and brave warrior. He was aided by the caliph’s best armies, commanding 6,000 Syrian cavalry and 3,000 camels for the mission. (Rahman, 2015)

Battle of Rawar

In the year 91AH (711), Muslim armies from Persia marched on the coast road while ships sailed in from Basra, carrying men and supplies which arrived in the seat port of Debal. The town was protected by a small force and contained a Buddhist temple, surrounded by stone walls. The Muslim fleets reached Muhammad ibn Qasim at the same time, overpowering pirates and sea robbers in the region. 

Ibn Qasim set camp near its walls and besieged it. He used a mangonel, a type of siege equipment which threw projectiles over walls. It demolished the Buddhist temple, before they entered the city by force and its governor fled. Several Muslims remained in the city, building a mosque there. The Muslim army continued to advance northwards towards Sindh where more cities were conquered. 

Meanwhile Raja Dahir gathered his army to crush the Muslims near the Indus River, commanding an army of 50,000 men, horses and elephants from Brahmanabad to Rawar. His aim was to push back the Arab advance and block them from crossing the river. He did this by sending his forces to the river's eastern bank. Muhammad ibn Qasim remained in contact with his uncle Al-Hajjaj for advice on crossing the river. The governor ordered his nephew to form a fleet of boats together to create a makeshift bridge.

The Muslim army tied the boats together with ropes which were long enough to span the rivers’ width. One end was tethered to the western bank and the other to the eastern side. After nearly 50 days of being camped on the Western bank, Muhammad ibn Qasim crossed the Indus River to confront the Hindu army near the fortress of Bet. (Al Omary, 2021, 214-5)

Dahir’s Death and Further Conquests

Raja Dahir was camped out in Rawar, not far from the Indus river. On June 20th 712 he ordered the attack on the Muslims, who fought fiercely against the larger Hindu army. The fighting resulted in Dahir being killed after being separated from his elephant. The Hindu army lost heart and fled from the battlefield, some fled to the capital Aror. The Muslim army was victorious and entered Rawar. Dahir's severed head was sent to Hajjaj ibn Yusuf after his defeat. The Raja’s devastated wife, Rani Bai burnt herself alive alongside her female handmaids in a practice known as Jauhar.

Muhammad ibn Qasim became the ruler of Sindh, and now controlled the whole of Indus Valley. He built mosques and financial and military networks. However, a new rebel army formed in Brahmanabad (modern day Hyderabad) led by Jai Singh, Dahir's son, which planned to attack the Muslims. Jai Singh and his army locked themselves in the capital while Muhammad ibn Qasim besieged the city, leading to Jai Singh fleeing and 8,000 Hindu soldiers killed. Brahmanabad fell to the Muslims and later Aror. The people of Aror received kind treatment and their temples were left intact. His army moved westwards to Sakkar which fell without any fighting. (Akhtari, 2015, 20-5)

The Muslims entered Multan which marked the furthest the Arabs reached in Sind. The town was rich with gold and its Buddhist temple was a pilgrimage centre. The natives put up a fierce resistance until the Muslim army cut the water supply running into the city. The inhabitants eventually surrendered. Muhammad ibn Qasim remained in the area and turned it into a hub for Muslims. Multan contained many treasures within its temples, gaining the title the House of Gold, which was distributed amongst the army. Ibn Qasim built mosques and organised its military and financial affairs. From Multan, Islam began to spread through these regions.  (Al Omary, 2021, 215)

Religious Leniency and Relationship with Locals

The conquests into India marked a new change for the Muslims who came into contact with religions outside the People of the Book. Many Hindus and Buddhists lived in Sindh. The new Muslim rulers decided Buddhist temples should be treated like Christian churches, Jewish synagogues, or Zoroastrian fire temples.

After being conquered, Brahmanabad's inhabitants requested leniency, asking that the artisans, traders and common folk were spared. Muhammad ibn Qasim granted their request. He also recruited local officials for the administration and conducted a census of the merchants and artisans. Both groups either converted to Islam or paid jiziyah (non-Muslim tax). Village chiefs were appointed to collect this tax.

The local Brahmin community gained status under the new regime. Ibn Qasim allowed Brahmin’s residents to rebuild a depleted temple and worship undisturbed after they interceded with him. Muhammad ibn Qasim’s pragmatism left the population able to continue their worship, and they trusted him enough to cooperate with the new administration. 

Ibn Qasim was shown to have a relationship with the religious class, treating them with leniency and at times humour.  In one instance when visiting a shrine at al-Rur he hid a bracelet from the arms of a statue and asked the temple's keeper where it had gone. The keeper realised it was missing and couldn't explain how. Ibn Qasim teased him, asking how a god didn't know who took the bracelet. Quickly, he reinstated the bracelet to the idol's arm and left the temple. (Kennedy, 2007, 303-5)

Rather than confront their pagan beliefs Muhammad ibn Qasim used an innocent joke to show the priest and worshippers their idol god could not help themselves. In this way, he taught Islamic principles, and left its population to their own customs and faith without violence or harassment. 

Political Turmoil and Death

Muhammad ibn Qasim remained in Sindh for three years when the news of Al-Hajjaj's death reached his army in 714. Uncertainty spread as his uncle had been his advisor throughout the campaign, providing strategies, men and supplies. After this Caliph Al-Walid sent orders to stop the advance into Sindh. The following year, the Caliph also dies, decreasing ibn Qasim’s supporters. 

Caliph Al-Walid was succeeded by his younger brother Sulayman ibn Abdul Malik who he’d been locked in a power struggle with. Sulayman had been named successor by their father Abdul-Malik, however Al-Walid unsuccessfully attempted to appoint his son. By the time Al-Walid died, the brothers’ relationship had soured. As the new caliph, Sulayman retaliated by punishing his brother's supporters. His targets included Musa ibn Nusayr, Qutayba ibn Muslim and the family of Hajjaj ibn Yusuf. 

Al-Hajjaj had been a bitter enemy to Caliph Sulayman due to his loyalty to Al-Walid. When he died, Hajjaj’s living relatives were attacked. This occurred after the new caliph dismissed Yazid ibn Abu Muslim as Iraq’s new governor, who'd been appointed by Al-Hajjaj to be his successor before his death. He was replaced by Salih ibn Abdur Rahman, whose brother had been killed by the former governor and bore a grudge against him. Sulayman ordered Salih to arrest and torture Hajjaj's family. As a result, Muhammad ibn Qasim was recalled to Iraq and imprisoned at Wasit. He died in captivity at the age of 20 in 715, 96 AH. (History of Islam, n.d.)

Conclusion: Legacy and Impact

Despite the actions of political rivals, Muhammad ibn Qasim's service to Islam is undisputable. In his short life the general laid the foundations of Muslim conquest into the Indian subcontinent, allowing Muslims to live at peace with Buddhists and Hindus. His death was mourned by the natives, who saw him as a man of humility and grace. By the end of the conquest, the Muslims owned much of the Indus valley and settled from Multan to the south of the river. This was all possible by the efforts of a 17 year old youth, whose bravery brought Islam to the Indian Subcontinent, where it remains alive and thriving today.

May Allah have mercy on Muhammad ibn Qasim  رَحِمَهُ ٱللَّٰهُ, raise his ranks and allow the youth to learn from his legacy and strive in the service of Islam, Ameen.
