The Book of Virtues
Witr Prayer, its Time and Ruling
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: مِنْ كُلِّ اللَّيْلِ قَدْ أَوْتَرَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ: مِنْ أَوَّلِ اللَّيْلِ ومن أوسطه، ومن آخره. وَانْتَهَى وِتْرُهُ إِلَى السَّحَرِ. ((مُتَّفَقٌ عَلَيْهِ))
'Aishah (May Allah be pleased with her) reported: The Messenger of Allah (ﷺ) observed Witr prayer in every part of night at the beginning, middle and at the last part. He (ﷺ), however, would finish his Witr prayer before dawn. [Al-Bukhari and Muslim].
