Tell me about the prayer of the Noble Prophet (S).” He (as) said: “The Holy Prophet (S) used to pray eight rak’ahs at midday and four (rak’ahs) in the first prayer (i.e. the Dhuhr prayer), then eight (rak’ahs) after this and four in the ‘Asr prayer. Three (rak’ahs) in Maghrib prayer, four after Maghrib, then four (rak’ahs) in ‘Isha prayer, eight for night prayers and then three for Witr. And (he prayed) two rak’ahs at dawn and two for the Fajr prayer.” I said: “May I be your ransom!
It is apparent from this narration that the utmah is considered to be separate from the fifty (daily prayers consisting of the daily obligatory and nawafil prayers). Its two rak’ahs, (performed while sitting) are counted as one rak’ah and it was prescribed as a precautionary replacement for the Witr prayer - in case someone dies in his sleep before being able to perform the Witr.
Al-Saduq has narrated in al-’Ilal: Narrating from Abi Basir from Abi ‘Abdillah (as) who said: The one who believes in Allah and the day of reckoning should not sleep until after having performed the Witr.
