A man whose age is approaching sixty-five does not fast or pray, and he loves to talk about lewd matters and drinks intoxicants. Is there an obligation on me regarding him?

Question:
May Allah reward you with good, and may He do you good. A listener named Ahmad Bukht from Tabuk asks and says: I know a man whose age is approaching sixty-five, who does not fast or pray, loves to talk about lewd matters, and drinks intoxicants. Is there an obligation on me regarding him? May Allah reward you with good.

Answer:
You have the obligatory duty of advising and calling to Allah the Exalted and Majestic toward this man and others. The Messenger (peace and blessings be upon him) said: So you must forbid him from these sins. In fact, abandoning the prayer and intentionally abandoning it is considered apostasy from Islam. Likewise, his abandoning of the pillars of Islam, such as fasting, is a matter of great severity. It is not your right, and it is not permissible for you, to overlook that, or to mix with this man or be his companion until you advise him and call to Allah the Exalted and Majestic. If he repents to Allah, then you have the reward, and Allah accepts the repentance of whoever repents. If he persists in what he is doing, then you must cut off ties with him and stay away from him, because he is an enemy of Allah and His Messenger; he does not pray, does not fast, drinks intoxicants, and commits lewd acts. It is not permissible to be his companion or to remain silent about his crimes. You must disapprove of him. If the matter leads to referring him to the authority, if there is an authority that can take action against him, then it is obligatory for you, after advising him and his persistence in what he is doing, to refer his case to the authority so that they take action against him. Yes.
