Sahih al-Bukhari 1151Book 19, Hadith 32
قَالَ وَقَالَ عَبْدُ اللَّهِ بْنِ مَسْلَمَةَ عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ كَانَتْ عِنْدِي امْرَأَةٌ مِنْ بَنِي أَسَدٍ فَدَخَلَ عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ " مَنْ هَذِهِ ". قُلْتُ فُلاَنَةُ لاَ تَنَامُ بِاللَّيْلِ. فَذُكِرَ مِنْ صَلاَتِهَا فَقَالَ " مَهْ عَلَيْكُمْ مَا تُطِيقُونَ مِنَ الأَعْمَالِ، فَإِنَّ اللَّهَ لاَ يَمَلُّ حَتَّى تَمَلُّوا ".
A woman from the tribe of Bani Asad was sitting with me and Allah's Apostle (p.b.u.h) came to my house and said, "Who is this?" I said, "(She is) So and so. She does not sleep at night because she is engaged in prayer." The Prophet (ﷺ) said disapprovingly: Do (good) deeds which is within your capacity as Allah never gets tired of giving rewards till you get tired of doing good deeds."
