Exactly, you know those who became ‘religious’, they look down on other Muslims, thinking they’re not ‘practising Muslims’, they think they’re like the ones who’s above everyone etc. This gives off arrogance and arrogance is a huge sin in Islam. Plus those ‘arrogant Muslims’ are a regular occurrence in the YouTube dawah scene where they commit zina etc and they get exposed.Bro you need to stop worrying about other people and worry about yourself. You are acting as if you are promised jannah and your post comes across as very arrogant to me. Either you are very young or you have recently started becoming religious. Life is too short to worry about other people’s sins. Why are caring so much about the sincerity of other people’s salah? What about your own salah? Who told you that you are a good Muslim?
