After Abu Sufyan had left Madina, the Holy Prophet ordered preparations to be made for a foray. The Holy Prophet mustered a force ten thousand strong and took the road to Makkah. Having reached in the neighborhood of Makkah, the Muslims encamped at Marr al Zahran. When at night fire was lit in the Muslim camp it appeared as if the whole of the desert was on fire. That alarmed the Quraish. Abu Sufyan realized that it would be futile for the Quraish to resist the Muslims. He visited the Muslim camp and was converted to Islam. That was the end of the Quraish opposition. The following day the Muslim army marched triumphantly into Makkah. The various contingents of the Muslim army marched into Makkah through different gates. Ali held the banner of Islam. The triumphant entry of the Muslims in Makkah marked the vindication of the truth of Islam. The city which eight years ago had treated the Muslims cruelly, and driven them to seek refuge with strangers in Madina now lay at the feet of the Muslims. In the hour of triumph, the Holy Prophet forgot every evil suffered, and forgave every injury that had been inflicted on him. He granted general amnesty to the people of Makkah.
