I went out with my father to visit ʿAli bin Abi Talib ؓ when he was sick and had become very ill. My father said to him: What is keeping you here? If you die, there will be no one to take care of your (burial) except the Bedouin of Juhainah. It is better for you to be carried to Madinah, then if you die your companions will take care of you and offer the funeral prayer for you, ‘Ali ؓ said: The Messenger of Allah ﷺ promised me that I would not die until I am appointed leader, then this - meaning his beard - will be dyed from the blood of this - meaning his head, Then he was killed, and Abu Fadalah was killed fighting alongside ‘Ali on the day of Siffeen.  

لَهُ أَبِي مَا يُقِيمُكَ بِمَنْزِلِكَ هَذَا لَوْ أَصَابَكَ أَجَلُكَ لَمْ يَلِكَ إِلَّا أَعْرَابُ جُهَيْنَةَ؟ تُحْمَلُ إِلَى الْمَدِينَةِ فَإِنْ أَصَابَكَ أَجَلُكَ وَلِيَكَأَصْحَابُكَ وَصَلَّوْا عَلَيْكَ فَقَالَ عَلِيٌّ إِنَّ رَسُولَ اللهِ ﷺ عَهِدَ إِلَيَّ أَنْ لَا أَمُوتَ حَتَّى أُؤَمَّرَ ثُمَّ تُخْضَبَ هَذِهِ يَعْنِي لِحْيَتَهُ مِنْ دَمِ هَذِهِ يَعْنِي هَامَتَهُ فَقُتِلَ وَقُتِلَ أَبُو فَضَالَةَ مَعَ عَلِيٍّ يَوْمَ صِفِّينَ
