Chapter : Disapproval of causing injury to anyone by a will.
Narated By Abu Hurairah : The Prophet (PBUH) said: A man or a woman acts in obedience to Allah for sixty years, then when they are about to die they cause injury by their will, so they must go to Hell. Then Abu Hurairah recited: “After a legacy which you bequeath or a debt, causing no injury… that will be the mighty success.
