Due to Muhammad's rushed actions, Ibrahim failed to co-ordinate his uprising with his brother's, and only declared himself two weeks before Muhammad's death, on 23 November.[1][2] Ibrahim's revolt at first met with quick success, securing control over Ahwaz, Fars and Wasit, and his army register (diwan) was said to number 100,000 names.[11] When the news of Muhammad's death arrived, the rebels acclaimed Ibrahim as his successor.[13] Ibrahim now was faced with a choice: a group of dedicated Alid supporters, which had managed to escape from Kufa, urged him to march on the city, while the Basrans preferred to stay in place and reach a negotiated settlement.[11] This dissension is indicative of the disparate nature of Ibrahim's supporters.
