The Excellence of Supplication for Those Who Are Absent

And all those who come after them (and follow in their footsteps) pray: “O our Lord! Forgive us and our brothers (and sisters) in Religion who have preceded us in faith, and let not our hearts entertain any ill-feeling against any of the believers. O our Lord! You are All-Forgiving, All-Compassionate (especially toward Your believing servants). (al-Hashr 59:10)
Ask forgiveness for your lapses, and for the believing men and believing women. (Muhammad 47:19)
Our Lord! Forgive me, and my parents, and all the believers, on the Day on which the Reckoning will be established. (Ibrahim 14:41)

720. Abu’d-Darda, may Allah be pleased with him, reported that he heard the Messenger of Allah, peace and blessings be upon him, say, “There is no Muslim slave who supplicates for his brother in his absence without an angel saying, ‘And for you the same.’” (Sahih Muslim, Dhikr, 86).
721. Usama ibn Zayd, may Allah be pleased with him, reported that the Messenger of Allah, peace and blessings be upon him, said, “Whoever has something good done for him and says to the one who did it, Jazakallahu khayr (May Allah repay your with good), has made full repayment.” (Sunan at-Tirmidhi, Birr, 87).
723. Abu Hurayra, may Allah be pleased with him, reported that the Messenger of Allah, peace and blessings be upon him, said, “The closest that a servant of Allah is to his Lord is while he is prostrating, so make a lot of supplication then.” (Sahih Muslim, Salah, 215).
