At his estate Amr received news of the Siege of Uthman and the Caliph's subsequent assassination by Amr's Egyptian partisans. The roughly 400–600 Egyptian mutineers had protested Uthman's fiscal centralization policies in Medina and accused him of favoring his relatives over the early Muslim converts. The Caliph persuaded them to withdraw, but after they intercepted a letter on their departure ordering Ibn Abi Sarh to punish them, they turned back and assaulted Uthman in his home. In an anecdote cited by al-Baladhuri, Amr is quoted taking partial credit for Uthman's killing. Ali succeeded Uthman, but did not reappoint Amr to his post in Egypt. Amr was one of a number of figures held culpable for Uthman's death by the slain caliph's clan, the Banu Umayya (Umayyads), most prominently by Uthman's uterine brother and Amr's former brother-in-law al-Walid ibn Uqba. Nonetheless, the governor of Syria—which included Palestine—the Umayyad Mu'awiya ibn Abi Sufyan, had left Amr on his estate undisturbed. As pressure from the Umayyads increased against him, Amr distanced himself from any role in Uthman's death and wrote Mu'awiya to execute or banish the participating Egyptian troops who had been apprehended when they passed through Mu'awiya's jurisdiction on their way back to Egypt.
