Allah, the Exalted, says:
"And ask forgiveness for your sin, and also for (the sin of)
believing men and believing women''. (47:19)
Abud-Darda' (May Allah be pleased with him) reported:
I heard the Messenger of Allah (PBUH) saying,
"Whenever a Muslim supplicates for his (Muslim) brother in
his absence, the angels say: `May the same be for you too'.''
[Muslim].
Commentary: This Hadith makes it evident that one who prays for
someone in his absence also stands to benefit from it because the
angel appointed for the task of praying for those who pray for others
will pray for him, saying,
"O Allah! Grant him also the same which he has asked for others.''

The Messenger of Allah (PBUH) said,
"The supplication of a Muslim for his (Muslim) brother in his absence
will certainly be answered. Everytime he makes a supplication for
good for his brother, the angel appointed for this particular task says:
`A meen! May it be for you, too'.''
[Muslim].
