And that is for those who even pray at all. There are those who have not only put aside their life’s purpose, they have abandoned it completely. What we often don’t realize about the abandonment of salah is this: No scholar has ever held the opinion that committing zina (fornication) makes you a disbeliever. No scholar has ever held the opinion that stealing, drinking or taking drugs makes you a disbeliever. No scholar has even claimed that murder makes you a non-Muslim. But, about salah, some scholars have said he who abandons it, is no longer Muslim. This is said based on ahadith such as this one: “The covenant between us and them is prayer, so if anyone abandons it, he has become a disbeliever.” [Ahmad]
This just reminded me of what i hear people say, they dont perform salah yet they say 'i dont steal drink or drugs or have a relationship with anyone and im proud to be muslim' etc i think people think that just being nice and following basic rules like not drinking alcohol etc makes u muslim...
