- .... Al-Ashtar al-Nakha'i was appointed to Egypt, and he had been the deputy over Mosul and Nisibis. He wrote to him, summoning him to return and appointing him to Egypt.
When this reached Mu'awiyah, that Al-Ashtar al-Nakha'i was appointed to Egypt instead of Muhammad ibn Abi Bakr, he knew that Al-Ashtar would defend it against him due to his boldness and bravery. So, Al-Ashtar set out for it, and when he reached Al-Qulzum, the Jayasar came out to meet him, who was the commander of Alayk on Kharaj, and he presented him with food and gave him a drink of honey, and he died from it. When Mu'awiyah and Amr and the people of Sham learned of this, they said: "Indeed, Allah has armies from honey."
- ....
Ibn Jarir mentioned in his history that Mu'awiyah had instructed this man to find a way to kill Al-Ashtar and promised him certain rewards for doing so, and he did it. There is some consideration in this, and even if it is true, Mu'awiyah would consider it permissible to kill Al-Ashtar because he was one of the murderers of Uthman (may Allah be pleased with him). The point is that Mu'awiyah and the people of Sham rejoiced greatly at the death of Al-Ashtar al-Nakha'i. When this reached Ali, he lamented his bravery and capabilities and wrote to Muhammad ibn Abi Bakr, confirming his stability and continuation in the land of Egypt.
