If a person drinks alcohol is his Salah (prayer) valid even though he knows that it is prohibited?
Is performing Salah related to drinking wine?
(Part No. 6; Page No. 23)
It is absolutely prohibited to drink alcohol at any time. Allah (Exalted be He) says:
Intoxicants (all kinds of alcoholic drinks), and gambling, and Al-Ansâb, and Al-Azlâm (arrows for seeking luck or decision) are an abomination of Shaitan’s (Satan) handiwork. So avoid (strictly all) that (abomination) in order that you may be successful.
If one performs Salah in a state of drunkenness and does not discern anything, his Salah will be invalid and he has to perform it again. If he is not drunk, his Salah will be valid.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
