Please be careful when telling off a fellow believer about certain indecent acts. One should approach them in private… it is for your own good.

Imam Sadiq (as) said: “The Messenger of Allah has said, ‘Whoever publicizes an indecent act is considered as the initiator of such deed and whoever rebukes a believer for a thing will not die before he himself commits such a thing.’”

Sanad: It is narrated from Ali ibn Ibrahim from his father from ibn abu ‘Umayr from Isma’il ibn ‘Ammar from Ishaq ibn Ammar
