Sahih al-Bukhari 996
Narrated 'Aisha:
Allah's Apostle offered Witr prayer at different nights at various hours extending (from the 'Isha' prayer) up to the last hour of the night.
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي مُسْلِمٌ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، قَالَتْ كُلَّ اللَّيْلِ أَوْتَرَ رَسُولُ اللَّهِ ﷺ وَانْتَهَى وِتْرُهُ إِلَى السَّحَرِ.
