The Book of Prayer - Travellers
Night prayers and the number of rak`ah offered by the Prophet (ﷺ) at night, and that Witr is one rak`ah, and a one-rak`ah prayer is correct
حَدَّثَنَا أَبُو كُرَيْبٍ، أَخْبَرَنَا ابْنُ بِشْرٍ، عَنْ مِسْعَرٍ، عَنْ سَعْدٍ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، قَالَتْ مَا أَلْفَى رَسُولَ اللَّهِ صلى الله عليه وسلم السَّحَرُ الأَعْلَى فِي بَيْتِي - أَوْ عِنْدِي - إِلاَّ نَائِمًا .
'A'isha reported: Never did the earlier part of the dawn find the Messenger of Allah (ﷺ) but sleeping in my house or near me.
