It was narrated that `Ali bin Abi Talib (رضي الله عنه) said:
The Prophet (ﷺ) wanted me to bring him something on which to write, by means of which his ummah would not be misguided after he was gone. “Ali said: I was afraid that he would die (before I could bring it). I said: I can memorise and understand. He said: “I urge you to pray and pay zakah and to be kind to those whom your right hands possess.”
