It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) looked towards Uhud and said: "By the One in whose Hand is my soul! It would not please me that this Uhud were turned into gold for the family of Muhammad, which I spend in the path of Allah, and that on the day I die I leave behind two dinars of it, except two dinars that I keep aside for a debt, if I have any debt."
