If alcohol falls on someone’s clothes, would his clothes become impure? If someone has performed Namaz while wearing such clothes, would his Salah be valid?
Alcohol is a type of Najasat-e-Ghalizah (Gross Impurity). If it falls on one’s clothes, it would make the clothes impure, and it would be necessary to repeat the Namaz performed while wearing such clothes.
And Allah knows best.
