Fatwa by: Former Grand Mufti of Saudi Arabia, Sheikh Ibn Baz (may Allah have mercy on him)
"The night prayer is offered in pairs of two. When one of you fears that dawn is approaching, let him pray one Rak'ah, which will make the prayer he has offered Witr." [Sahih al-Bukhari and Sahih Muslim]
Question:
What is the last time for performing Witr prayer to the best extent possible?Answer:
The time for performing the Witr prayer lasts until the appearance of Fajr (the true dawn). The Prophet (peace and blessings be upon him) said:"The night prayer is offered in pairs of two. When one of you fears that dawn is approaching, let him pray one Rak'ah, which will make the prayer he has offered Witr." [Sahih al-Bukhari and Sahih Muslim]
