Muwatta Imam Malik Book of Tahajjud, Hadith 5

Yahya related to me from Malik from Ismail from Ibn Abi Hakim that he had heard that the Messenger of Allah ﷺ heard a woman praying at night. He said, "Who is that?" and someone said to him,"It is al-Hawla bint Tuwayt, she does not sleep in the night." The Messenger of Allah ﷺ disapproved of that and his disapproval showed in his face. Then he said, "Allah, the Blessed and Exalted, does not become weary, but you become weary. Take on whatever is within your capability."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي حَكِيمٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ ﷺ سَمِعَ امْرَأَةً مِنَ اللَّيْلِ تُصَلِّي فَقَالَ " مَنْ هَذِهِ " . فَقِيلَ لَهُ هَذِهِ الْحَوْلاَءُ بِنْتُ تُوَيْتٍ لاَ تَنَامُ اللَّيْلَ . فَكَرِهَ ذَلِكَ رَسُولُ اللَّهِ ﷺ حَتَّى عُرِفَتِ الْكَرَاهِيَةُ فِي وَجْهِهِ ثُمَّ قَالَ " إِنَّ اللَّهَ تَبَارَكَ وَتَعَالَى لاَ يَمَلُّ حَتَّى تَمَلُّوا اكْلَفُوا مِنَ الْعَمَلِ مَا لَكُمْ بِهِ طَاقَةٌ " .
