On the excellence of supplication

by Imam Nawawi

251. Chapter: On the excellence of supplication for those who are absent

Allah says, "And those who have come after them say: 'Our Lord, forgive us and our brothers who preceded us in faith," (59:10)

and He says, "Ask forgiveness for your wrongdoing, and for the men and women who believe." (W47:20; H47:19)

The Almighty says, reporting from Ibrahim, "Our Lord! Forgive me and my parents and the believers on the Day the Reckoning takes place." (W14:43; H14:41)

1494. Abu'd-Darda' reported that he heard the Messenger of Allah, may Allah bless him and grant him peace, say, "There is no Muslim slave who supplicates for his brother in his absence without an angel saying, 'And for you the same.'" [Muslim]

1495. Abu'd-Darda' reported that the Messenger of Allah, may Allah bless him and grant him peace, used to say, "A supplication which a Muslim man makes secretly for his brother is answered. At his head is a guardian angel. Whenever he makes supplication for good for his brother, the angel who guards him says, 'Amen, and for you the same.'" [Muslim]
