Answered by Shaykh Faraz Rabbani
Question: Assalam ‘aleykum,
What happens if you accidentally consume alcohol? Do you have to renew your wudu?Answer: walaikum assalam wa rahmatullah,
I pray this finds you in the best of health and spirits.
Consuming the haram–such as alcoholic beverages–does not invalidate one’s ritual ablution (wudu’). If done deliberately or in negligence, remorse and repentance is needed. One must rinse out one’s mouth, though, as wine is filthy (najis).

And Allah is the giver of success and facilitation.
