[Machine] On the authority of Abu Usaid, companion of the Messenger of Allah ﷺ , who was present at the Battle of Badr and was their guardian. He said, Abu Usaid said, "While I was sitting with the Messenger of Allah ﷺ , a man from the Ansar came to him and said, 'O Messenger of Allah, is there any act of goodness that I can do for my parents after their death to benefit them?' He said, 'Yes, four characteristics: Praying for them, seeking forgiveness for them, fulfilling their promises, and honoring their friends. And maintaining family ties that do not exist except through them. These are the acts of goodness that remain for you to do for them after their death.'"
