Malik :: Book 3 : Hadith 3.12.49

Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "When one of you says 'Amin' and the angels in the sky say 'Amin' so that one coincides with the other, his previous wrong actions are forgiven him."
