Question: What is the ruling of cursing the sinner of [the command of] Allaah in a certain matter, even if the sin was minor?
Response: Sinning is known [by] abandoning that which is obligatory [upon oneself] or doing that which is prohibited, and the sinner from amongst the Muslims is advised, and advising is obligatory upon every Muslim according to his ability.
The Messenger of Allaah (sal-Allaahu ‘alayhe wa sallam) said:
«He who amongst you sees something abominable should modify it with the help of his hand; and if he has not strength enough to do it, then he should do it with his tongue; and if he has not strength enough to do it, [even] then he should [abhor it] from his heart and that is the least of faith.», [transmitted by Muslim, 49]
And [Allaah] The Most High says:
{Help you one another in al-Birr and at-Taqwa (virtue, righteousness and piety)}, [Soorah al-Maa.idah, Aayah 2]
As for backbiting the Muslim, then that is prohibited even if he was a sinner, unless if someone sought your advice for [an issue related to] a transaction, then it is upon you to explain.
