Sunan Abi Dawud 1368
Narrated 'Aishah:
The Messenger of Allah (ﷺ) as saying: Choose such actions as you are capable of performing, for Allah does not grow weary till you do. The acts most pleasing to Allah are those which are done most continuously, even if they amount to little. Whenever he began an action, he would do it continuously.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ عَجْلاَنَ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، - رضى الله عنها - أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏:‏ ‏
"‏ اكْلَفُوا مِنَ الْعَمَلِ مَا تُطِيقُونَ، فَإِنَّ اللَّهَ لاَ يَمَلُّ حَتَّى تَمَلُّوا، وَإِنَّ أَحَبَّ الْعَمَلِ إِلَى اللَّهِ أَدْوَمُهُ وَإِنْ قَلَّ ‏"‏ ‏.‏ وَكَانَ إِذَا عَمِلَ عَمَلاً أَثْبَتَهُ ‏.‏
