Hadith 311
حَدَّثَنَا أَبُو هِشَامٍ مُحَمَّدُ بْنُ يَزِيدَ الرِّفَاعِيُّ قَالَ: حَدَّثَنَا ابْنُ فُضَيْلٍ، عَنِ الْأَعْمَشِ، عَنْ أَبِي صَالِحٍ قَالَ : سَأَلْتُ عَائِشَةَ، وَأُمَّ سَلَمَةَ، أَيُّ الْعَمَلِ كَانَ أَحَبَّ إِلَى رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ؟ قَالَتَا: «مَا دِيمَ عَلَيْهِ وَإِنْ قَلَّ»
Abu Salih reports that Umm al-Mu'minin Sayyida Aisha Siddiqa (may Allah be pleased with her) and Sayyida Umm Salama (may Allah be pleased with her) were asked: "Which deed was most beloved to the Messenger of Allah (peace and blessings be upon him)?" They replied: "That which is done consistently, even if it is little."
