Narrated 'Aisha:

A woman from the tribe of Bani Asad was sitting with me and Allah's Apostle ﷺ 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."

حَدَّثَنَا أَبُو مَعْمَرٍ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ دَخَلَ النَّبِيُّ ﷺ فَإِذَا حَبْلٌ مَمْدُودٌ بَيْنَ السَّارِيَتَيْنِ فَقَالَ " مَا هَذَا الْحَبْلُ ". قَالُوا هَذَا حَبْلٌ لِزَيْنَبَ فَإِذَا فَتَرَتْ تَعَلَّقَتْ. فَقَالَ النَّبِيُّ ﷺ " لاَ، حُلُّوهُ، لِيُصَلِّ أَحَدُكُمْ نَشَاطَهُ، فَإِذَا فَتَرَ فَلْيَقْعُدْ ".
