The Ruling on Boycotting the Sinner

Question:
May Allah reward you, Your Eminence, father. The questioner says: I have a brother who abandons prayer and uses narcotics. I have advised him many times, but he did not respond, so I boycotted him. Is boycotting him in this case correct? My father went with him to get him married. I explained his situation to my father and advised him not to go with him, but he refused. Is what my father did permissible? And by doing this, am I free of blame?

Answer:
Boycotting the sinner requires a distinction. If boycotting him serves as a deterrent for him, so that he may perhaps return and repent, then this is required, and he should be boycotted. The Prophet (peace and blessings be upon him) boycotted the three who were left behind for fifty days until Allah turned to them in mercy. However, if boycotting him only increases the evil, then one is not rewarded for it; rather, one should advise him and continue advising him, and marry him off, so that Allah may protect him and prevent the cause of his marriage, which is, by the permission of Allah, a cause for his protection and guidance, by the permission of Allah. So do not prevent your father from marrying him off or from going with him to advise him and look after him. Yes.
