It was narrated that Abu Sa'eed Al-Khudri said:"The Messenger of Allah said: 'Whoever leaves his house for the prayer and says: 'Allahumma inni asa'luka bi-haqqis-sa'ilina 'alaika, wa as'aluka bi-haqqi mamshaya hadha, fa inni lam akhruj asharan wa la batran, wa la riya'an, wa la sum'atan, wa kharajtu-ttiqa'a sukhtika wabtigha'a mardatika, fa as'aluka an tu'idhani minan-nari wa an taghfira li dhunubi, Innahu la yaghfirudh-dhunuba illa Anta. (O Allah, I ask You by the right that those who ask of You have over You, and I ask by virtue of this walking of mine, for I am not going out because of pride or vanity, or to show off or make a reputation, rather I am going out because I fear Your wrath and seek Your pleasure. So I ask You to protect me from the Fire and to forgive me my sins, for no one can forgive sins except You),' Allah will turn His Face towards him and seventy thousand angels will pray for his forgiveness."
