Hadith 164

Sahih Muslim

Book 6: The Book of Prayer - Travellers

Chapter 17

Night prayers and the number of rak`ah offered by the Prophet (saws) at night, and that Witr is one rak`ah, and a one-rak`ah prayer is correct

باب صَلاَةِ اللَّيْلِ وَعَدَدِ رَكَعَاتِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي اللَّيْلِ وَأَنَّ الْوِتْرَ رَكْعَةٌ وَأَنَّ الرَّكْعَةَ صَلاَةٌ صَحِيحَةٌ

Sahih Muslim 744b
وَحَدَّثَنِي هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي سُلَيْمَانُ بْنُ بِلاَلٍ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي صَلاَتَهُ بِاللَّيْلِ وَهِيَ مُعْتَرِضَةٌ بَيْنَ يَدَيْهِ فَإِذَا بَقِيَ الْوِتْرُ أَيْقَظَهَا فَأَوْتَرَتْ ‏.‏
'A'isha reported that the Messenger of Allah (ﷺ) used to offer prayer at night while she lay in front of him, and when the Witr prayer was yet to be observed, he would awaken her and she observed Witr.
