This copy is the will of Amirul Momineen (a.s) to Imam Hasan Mujtaba (a.s) and it is also mentioned in Kitab Sulaym Ibn Qays Hilali, which he read out to Aban and Aban also said: I read out this will to Ali bin Husain (a.s) and he (a.s) said: Sulaym has said the truth, may Allah have mercy on him. [Imam Muhammad Baqir (a.s) said:] Sulaym has said: When Amirul Momineen (a.s) made a bequest to his son, Imam Hasan (a.s), I witnessed it. The Imam made Husain (a.s), Muhammad bin Hanfiyyah, all his sons and elders of Shia and his Ahle Bayt witness this bequest and in his address to Imam Hasan (a.s), he said: My son, the Messenger of Allah (s) ordered me to make a will in your favor and transfer my books and weapons to you. After that he glanced at Imam Hasan (a.s) and said: My son, you are my successor and inheritor of my blood; if you like you have the discretion to forgive my killer; and if you like you can put him to death; but retaliate one hit only with a single hit and don’t fall into sin. Thus he mentioned the rest of the will till the end. When the will of the Imam ended, he said: May Almighty Allah protect you and guard the practice of your Prophet among you. I entrust you to Almighty Allah about you and invoke His peace and blessings for you. After that the Imam continued: ‘There is no god, except Allah,’ till he passed on the 23rd night of Ramadhan, Friday eve in the 40th year A.H. due the fatal injury that he had received on the 21st of Ramadhan.
