Sunan Ibn Majah, Volume 5, Book 37, Hadith 4238 (DarusSalam) ⓘ

It was narrated that ‘Aishah said: “There was a woman with me, and the Prophet entered upon me and said: ‘Who is that?’ I said: ‘So-and-so; she does not sleep,’” – she mentioned her excessive praying. “The Prophet said: ‘Keep quiet. You should do what you are able to, for by Allah, Allah does not get tired (of giving reward) but you get tired.’” She said: “The most beloved of religious deed to him was that in which a person persists.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ ‏:‏ كَانَتْ عِنْدِي امْرَأَةٌ فَدَخَلَ عَلَىَّ النَّبِيُّ ـ صلى الله عليه وسلم ـ فَقَالَ ‏:‏ ‏"‏ مَنْ هَذِهِ ‏"‏ ‏.‏ قُلْتُ ‏:‏ فُلاَنَةُ ‏.‏ لاَ تَنَامُ - تَذْكُرُ مِنْ صَلاَحِهَا - فَقَالَ النَّبِيُّ ـ صلى الله عليه وسلم ـ ‏:‏ ‏"‏ مَهْ عَلَيْكُمْ بِمَا تُطِيقُونَ فَوَاللَّهِ لاَ يَمَلُّ اللَّهُ حَتَّى تَمَلُّوا ‏"‏ ‏.‏ قَالَتْ ‏:‏ وَكَانَ أَحَبَّ الدِّينِ إِلَيْهِ الَّذِي يَدُومُ عَلَيْهِ صَاحِبُهُ ‏.‏
