Would the Five Obligatory Daily Prayers be invalid if one does not offer the Witr?
Q 1: Are the Fajr (Dawn), Zhuhr (Noon), `Asr (Afternoon), Maghrib (Sunset), and `Isha' (Night) Prayers invalid
if a Muslim does not perform Witr (Prayer with an odd number of units) after `isha'?
Please advise us, May Allah reward you!
According to the stronger of the two opinions of the scholars, Witr Prayer is a stressed act of Sunnah (whatever is reported from the Prophet). Whoever observes it will be rewarded while whoever abandons it will not be punished. Therefore, abandoning an act of Sunnah does not invalidate the Five Obligatory Daily Prayers which are performed before Witr. They are only nullified by Shirk (associating others with Allah in His Divinity or worship), Riddah (apostasy), or not observing any of prayer's pillars or conditions. A Muslim should be keen on observing Witr Prayer in compliance with the example of the Messenger of Allah (peace be upon him). It was authentically reported that the Messenger of Allah (peace be upon him) used to offer Witr Prayer whenever at home or in a journey. It is better for a Muslim not to miss this great reward from Allah (Exalted be He).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
