Chapter 3: The Command to Pray the Witr
Muwatta Malik 275
Yahya related to me from Malik that he had heard that A'isha, the wife of the Prophet ﷺ used to say, "If someone fears that he will sleep through till the morning, let him pray the witr before he sleeps, and if someone hopes to wake for the last part of the night, let him delay his witr."
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم كَانَتْ تَقُولُ مَنْ خَشِيَ أَنْ يَنَامَ حَتَّى يُصْبِحَ فَلْيُوتِرْ قَبْلَ أَنْ يَنَامَ وَمَنْ رَجَا أَنْ يَسْتَيْقِظَ آخِرَ اللَّيْلِ فَلْيُؤَخِّرْ وِتْرَهُ .
