Sunan Ibn Majah, Book 4, Hadith 42 (In-Book) ⓘ
It was narrated from Abu Sa'eed Al-Khudri that : He heard the Messenger of Allah say: 'Shall I not tell you of something by means of which Allah expiates for sins and increases good deeds?' They said: 'Yes, O Messenger of Allah.' He said: 'Performing ablution properly despite difficulties, increasing the number of steps one takes towards the mosque and waiting for the next prayer after prayer.'
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَحْيَى بْنُ أَبِي بُكَيْرٍ، حَدَّثَنَا زُهَيْرُ بْنُ مُحَمَّدٍ، عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَقُولُ " أَلاَ أَدُلُّكُمْ عَلَى مَا يُكَفِّرُ اللَّهُ بِهِ الْخَطَايَا وَيَزِيدُ بِهِ فِي الْحَسَنَاتِ " . قَالُوا بَلَى يَا رَسُولَ اللَّهِ . قَالَ " إِسْبَاغُ الْوُضُوءِ عِنْدَ الْمَكَارِهِ وَكَثْرَةُ الْخُطَى إِلَى الْمَسَاجِدِ وَانْتِظَارُ الصَّلاَةِ بَعْدَ الصَّلاَةِ " .
