Al-Hajjaj Ibn Yoosuf At-Thaqafee, the leader of Iraq was sitting in his court encompassed by his dignitaries and armed force commandants (head of staffs). They were talking about the issues of the state attempting to track down answers for individuals' concerns. One of Al-Hajjaj's men entered and murmured a words to him, so he halted the discussion and said uproariously: "Let him enter right away!"
The man entered with a message and told Al-Hajjaj: "This is an earnest message that has quite recently been brought by the courier from 'Sindh' domains". Al-Hajjaj took the message and started to understand it. Before he had gotten done, he stood up unexpectedly in a fury. The specialists got stressed, and one of them said:
"May Allah correct your issues? Information exchanged in this message to agitate you? Has anything wrong happened to the Caliph 'Al-Waleed Ibn 'Abdul-Malik'? Has any of our adversaries gone after any piece of our property?"
Al-Hajjaj didn't represent some time then he emitted in a fury and began to let them know the substance of the message. He said, "The lord of the island of Sri Lanka sent us a few ships loaded with gifts. Ready, there were a few Muslim ladies. On their way, a few privateers from the city of 'Daibul' (a port at the mouth of the Waterway Sindh in Pakistan) went after it. They took the gifts and accepted the ladies as prisoners.
At the point when Al-Hajjaj became quiet, he composed a message to 'Dahir' the lord of Sindh requesting him to deliver the Muslim ladies, yet the ruler couldn't do as such. He made an impression on Al-Hajjaj letting him know that the prisoners had been gotten by infamous hoodlums and that he was unable to protect them. Al-Hajjaj was not persuaded with the response of the lord of Sindh, so he expected to rebuff those privateers and reestablish pride to the Muslims. He sent a tactical campaign to battle the privateers, yet they were totally crushed on the place that is known for Sindh. Along these lines, he sent another campaign, yet it likewise neglected to satisfy its main goal.
After the loss of his undertakings, Al-Hajjaj understood that he should design and plan himself so his foes wouldn't misjudge the Muslim state. He planned to send a colossal armed force to overcome the regions of Sindh, spread Islam there, and assist its kin with disposing of the foul play of their lead representatives. Simultaneously, he needed to get the boundaries of the Islamic state and shipping lanes. He sent for the Umayyad Caliph in Damascus Al-Waleed Ibn 'Abdul-Malik' requesting his authorization to plan and prepare the military. It took Al-Hajjaj a few months to set up the military and enroll huge number of experienced and fearless troopers. He outfitted them with the most impressive weapons, supplies, and food adequate for their undertaking.
Subsequent to setting up the military, he started to survey the names of the military chiefs he had to pick one who could satisfy this mission. Then he chose to pick his cousin Muhammad Ibn Al-Qaasim whose standing had started to increment despite the fact that he was still under twenty years of age. He was an arising star who was known for his power, grit, and expertise in procedures of war and undertaking military missions. He been able to lead fighters to triumph. He showed restraint in battling and firm in the front line. The news that Muhammad Ibn Al-Qasim had been decided to lead the military, spread, so the troopers were hopeful and were certain that Allah would concede them triumph. The youthful pioneer started to overview the military arrangements, set the tactical plans, investigated his adversary's situation, and came to know the marks of their power and shortcoming. At the point when he was certain that everything was all prepared, he requested his officers to withdraw.
The military set out towards its objective, completely prepared and completely ready. The troopers were yelling "Allahu Akbar" (Allah is the Best). At the point when the military came to 'Makran', they rested there for certain days. The youthful pioneer began to divide his military into two divisions. One division went through the land course and the other through the ocean.
Then, at that point, Muhammad Ibn Al-Qasim went to the city of 'Daibul' and begun to assault it. All of this occurred on Rabee' Al-Awwal, 89 A.H. Simultaneously, the Islamic warships conveying the officers, supplies, and weapons showed up. They totally assaulted the city. The pioneer requested the troopers to hit the city with slings and to focus on the colossal symbol that was being loved by individuals of the city. This icon was named 'Budh'. The icon was annihilated under the weighty stone shots of the launch.
The brave warriors ascended the walls of the city utilizing ropy stepping stools. Following three days of the attack, the Muslims had the option to flood into the city after the fighters of 'Dahir - the ruler of Sindh - got away.
The Muslims entered the city and treated its kin with equity and graciousness. Muhammad Ibn Al-Qasim wanted to lay out a camp for the Muslims in the city and he fabricated a mosque there. He likewise pre-arranged the city to be an ocean base for Muslims in the Indian Sea.
After Muhammad Ibn Al-Qasim was certain the city of 'Daibul' was steady, he left some Islamic gatekeeper powers there. Then, at that point, he drove his military to vanquish more urban communities. He won every one of the fights since he simply battled to liberate all individuals from servitude and oppression, and to execute equity and spread harmony and security.
The approach of Muhammad Ibn Al-Qasim towards individuals of Sindh urged many individuals to go along with him. He vanquished every one of the regions of Sindh in a steady progression yet, he was not content until all Sindh become under the Islamic state. He battled with Dahir who needed to snare Muhammad Ibn Al-Qasim by hauling him inside the city and afterward kill him.
Muhammad Ibn Al-Qasim understood the lord's arrangement, so he arranged his own arrangement that would astound the ruler. He crossed the waterway of 'Mahran' around evening time with huge number of his fighters. Following not many hours, the entire armed force was on the opposite side confronting the multitude of 'Dahir'.
In the first part of the day, the fight erupted and Dahir was driving the fight on the rear of an elephant encompassed by different elephants. The fight went on for not many hours, and the Muslims were triumphant. Dahir was killed, and his officers were dissipated and took off from the war zone.
After this incredible triumph, Muhammad Ibn Al-Qasim kept vanquishing the leftover domains of Sindh. He began to lay out the groundworks of the Islamic rule. He spread equity, so individuals invited him and gave their devotion to the Muslims who safeguarded their spirits and cash. A ton of them became Muslims and their reaction to Islam was perfect notwithstanding their different social foundations. Notwithstanding the general population, lead representatives, pioneers, priests, and rulers of various regions became Muslims like sovereign Kakah Ibn Jandar the cousin of Dahir the lord of Sindh.
