حَدَّثَنَا أَبُو هِشَامٍ مُحَمَّدُ بْنُ يَزِيدَ الرِّفَاعِيُّ، قَالَ: حَدَّثَنَا ابْنُ فُضَيْلٍ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، قَالَ: سَأَلْتُ عَائِشَةَ، وَأُمَّ سَلَمَةَ، أَيُّ الْعَمَلِ كَانَ أَحَبَّ إِلَى رَسُولِ اللهِ صلى الله عليه وسلم؟ قَالَتَا: مَا دِيمَ عَلَيْهِ، وَإِنْ قَلَّ.
"I asked 'A'isha and Umm Salama: “Which work was dearest to Allah’s Messenger (Allah bless him and give him peace)?” They said: “That which a person perseveres in, even if the amount of work done is small.”
