It was narrated that Anas said: "When this Verse was revealed -'By no means shall you attain Al Birr (piety, righteousness--here it means Allah's reward, i.e. Paradise), unless you spend (in Allah's cause) of that which you love'- Abu Talha said: “Our Lord will ask us about our wealth. I adjure you, O Messenger of Allah! I am giving my land to Allah.' The Messenger of Allah said: “Make it for your relatives, Hassan bin Thabit and Ubayy bin Ka'b””"
