Sahih al-Bukhari
Book 14: Witr Prayer
كتاب الوتر
15 hadith in this book
Narrated Anas bin Seereen:
I asked Ibn `Umar, "What is your opinion about the two rak`at before the Fajr (compulsory) prayer, as to prolonging the recitation in them?" He said, "The Prophet (ﷺ) used to pray at night two rak`at followed by two and so on, and end the prayer by one rak`ah witr. He used to offer two rak`at before the Fajr prayer immediately after the Adhan." (Hammad, the sub-narrator said, "That meant (that he prayed) quickly.)"
حَدَّثَنَا أَبُو النُّعْمَانِ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، قَالَ حَدَّثَنَا أَنَسُ بْنُ سِيرِينَ، قَالَ قُلْتُ لاِبْنِ عُمَرَ أَرَأَيْتَ الرَّكْعَتَيْنِ قَبْلَ صَلاَةِ الْغَدَاةِ أُطِيلُ فِيهِمَا الْقِرَاءَةَ فَقَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّي مِنَ اللَّيْلِ مَثْنَى مَثْنَى، وَيُوتِرُ بِرَكْعَةٍ وَيُصَلِّي الرَّكْعَتَيْنِ قَبْلَ صَلاَةِ الْغَدَاةِ وَكَأَنَّ الأَذَانَ بِأُذُنَيْهِ. قَالَ حَمَّادٌ أَىْ سُرْعَةً.
Narrated `Aisha:
Allah's Messenger (ﷺ) 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 صلى الله عليه وسلم وَانْتَهَى وِتْرُهُ إِلَى السَّحَرِ.
