Ali, peace be on him, was the testamentary trustee (wasi) of the Commander of the faithful, peace be on him, over his family, his children and his followers. He bequeathed him to look after his position and (the position of) his taxes (sadaqat) and he wrote him a covenant (of succession) which is well-known. His testamentary trusteeship is obvious in terms of the outlines of religion, the essential characteristic of wisdom and good-breeding.
A great number of scholars have reported this trusteeship and many of the men of understanding have realised the truth of this through his (attitude to) the world. Al-Hasan's Succession to the Caliphate and his Abdication When the Commander of the faithful, peace be on him, died, al- Hasan addressed the people. He reminded them of his right (to authority).
The followers of his father pledged allegiance to him in terms of fighting those he fought and making peace with those with whom he made peace. [Abu Mikhnaf Lut b. Yahya al-Azdi reported: Ashath b. Suwar told me on the authority of Abu Ishaq al-Sabi'i and others, who said;] Al-Hasan b. Ali, peace be on them, addressed the people towards dawn on the night in which the Commander of the faithful, peace be on him, died.
He praised and glorified God and blessed the Apostle of God, may God bless him and his family. Then he said: There has died tonight a man who was the first among the early (Muslims) in (good) actions. Nor did any later (Muslims) attain his level in (good) actions. He used to fight alongside the Apostle of God, may Allah bless him and his family, and protect him with his own life.
The Apostle of God, may God bless him and his family, used to send him forward with his standard while Gabriel supported him on his right and Michael supported him on his left. He would not return until God brought victory through his hands. He, peace be on him, has died on this the night on which Jesus, son of Mary, was taken up (to Heaven), on which Joshua, son of Nuh, the testamentary trustee (wasi) of Moses, peace be on him, died.
He has left behind him no gold and silver except seven hundred dirhams of his stipend (ata'), with which he was intending to buy a servant for his family. Then tears overcame him and he wept and the people wept with him. Then he continued: I am the (grand) son of the one who brought the good news. I am the (grand) son of the warner. I am the (grand) son of the man who, with God's permission, summoned (the people) to God.
