حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا مُوسَى بْنُ سَالِمٍ أَبُو جَهْضَمٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عُبَيْدِ اللَّهِ بْنِ عَبَّاسٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ أَمَرَنَا رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ بِإِسْبَاغِ الْوُضُوءِ ‏.‏
Translation
It was narrated from Abu Sa'eed 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: "Perform ablution properly despite difficulties, increasing the number of steps one takes towards the mosque and waiting for the next prayer after prayer.'"
