Hadith 1001

Narrated Ibn `Umar: Once a person asked Allah's Messenger (ﷺ) about the night prayer. Allah's Apostle (ﷺ) replied, "The night prayer is offered as two Rak`at followed by two Rak`at and so on and if anyone is afraid of the approaching dawn (Fajr prayer) he should pray one Rak`ah and this will be a Witr for all the Rak`at which he has prayed before

Nafi` told that `Abdullah bin `Umar used to say Taslim between (the first) two Rak`at and (the third) odd one in the Witr prayer, when he wanted to attend to a certain matter (during that interval between the Rak`at)

Narrated Ibn `Abbas:Once I passed the night in the house of Maimuna (his aunt). I slept across the bed while Allah's Apostle and his wife slept length-wise. The Prophet (ﷺ) slept till midnight or nearly so and woke up rubbing his face and recited ten verses from Surat "Al-`Imran." Allah's Messenger (ﷺ) went towards a leather skin and performed ablution in the most perfect way and then stood for the prayer. I did the same and stood beside him. The Prophet (ﷺ) put his right hand on my head, twisted my ear and then prayed two rak`at five times and then ended his prayer with witr. He laid down till the Mu'adh-dhin came then he stood up and offered two rak`at (Sunnah of Fajr prayer) and then went out and offered the Fajr prayer. (See Hadith)

Narrated `Abdullah bin `Umar:The Prophet (ﷺ) said, "Night prayer is offered as two rak`at followed by two rak`at and so on, and if you want to finish it, pray only one rak`a which will be witr for all the previous rak`at." Al-Qasim said, "Since we attained the age of puberty we have seen some people offering a three-rak`at prayer as witr and all that is permissible. I hope there will be no harm in it
