Umm ad-Darda' said, "Abu 'd-Darda' stood up in the night to pray. He was weeping and said, 'O Allah! You made my physical form good, so make my character good!' until morning. I said, 'Abu 'd-Darda', your only supplication for the entire night was for good character!' He replied, 'Umm ad-Darda', the Muslim makes his character good with the result that his good character takes him into the Garden. He makes his character bad with the result that his bad character takes him into the Fire. The Muslim is forgiven while he is asleep.' I asked, 'Abu 'd-Darda', how can be forgiven while he is asleep?' He said, 'His brother arises in the night and performs the night prayers and makes supplication to Allah Almighty and is answered. He makes supplication for Muslim brother and his request is answered.'"
