Abu Salama bin 'Abdur Rahman أبو سلمة بن عبد الرحمن بن عوف · Knowledge (Kitab Al-Ilm)

When Mecca was conquered, the Holy Prophet (peace be upon him) stood up. He (Abu Hurairah) then mentioned the sermon of the Holy Prophet (ﷺ). He said: A man of the Yemen, who was called Abu Shah, got up and said: Messenger of Allah! Write it for me. He said: Write it for Abu Shah.

I swear on Allah, it will be better for you that Allah should give guidance to one man through your agency than that you should acquire the red ones among the camels.
