Abu Hurairah narrated that : Allah's Messenger said: "Shall I tell you that for which Allah will wipe out your sins, and raise your ranks?" They said, "Of course Allah's Messenger!"

حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ، أَخْبَرَنَا إِسْمَاعِيلُ بْنِ جَعْفَرٍ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " أَلاَ أَدُلُّكُمْ عَلَى مَا يَمْحُو اللَّهُ بِهِ الْخَطَايَا وَيَرْفَعُ بِهِ الدَّرَجَاتِ " . قَالُوا بَلَى يَا رَسُولَ اللَّهِ . قَالَ " إِسْبَاغُ الْوُضُوءِ عَلَى الْمَكَارِهِ وَكَثْرَةُ الْخُطَا إِلَى الْمَسَاجِدِ وَانْتِظَارُ الصَّلاَةِ بَعْدَ الصَّلاَةِ فَذَلِكُمُ الرِّبَاطُ " .
