Ruling on boycotting a brother who abandons prayer after being advised

This questioner, Muhammad Alawi Qa'id, is of Yemeni nationality. He also asks and says: I have a brother from both my father and my mother who does not pray. I have advised him and explained to him what Allah has promised for one who cuts off prayer in this world and the Hereafter, and the torment he will face in the grave. But he did not respond to the call. He has spent about four years with me in a foreign land, and I have been advising him, but to no avail. The question is: Is it permissible for me to boycott him? Is it permissible to return his greeting? And if I boycott him and this boycott causes my mother to be angry with me, is there any sin on me for that? He also asks about eating and drinking with him, and so on.
Answer: You have done well in advising him and continuing to do so. As for his persisting in abandoning prayer and not being guided to accept the advice, that is up to Allah (Glorified and Exalted is He), for He guides whom He wills and misguides whom He wills. So you must supplicate to Him for him frequently for guidance, and likewise the mother should supplicate for his guidance: that Allah will guide him and turn him back to the right path. Do this in prostration at the end of the prayer, and at times when supplication is likely to be answered, such as the last part of the night, or between the adhan and the iqamah, perhaps Allah will guide him and perhaps Allah will accept your supplication and the mother's. As for boycotting, it is obligatory to boycott him as long as he does not accept; it is obligatory to boycott him and cut him off, perhaps he will benefit from this boycott and perhaps Allah will guide him through it. Do not take him as a companion who is your eating or drinking partner, and do not accept his invitation if he is in another house and invites you. Rather, show him your boycott and hatred until Allah Mighty and Majestic guides him. Likewise, the mother must disapprove of him and she must hate him for the sake of Allah, and she must boycott him until Allah guides him; because abandoning prayer is major shirk (associating partners with Allah) in the correct opinion of the scholars. The Prophet (peace and blessings be upon him) said: And the Prophet (peace and blessings be upon him) also said: , and he (peace and blessings be upon him) said: So prayer is the pillar of Islam; whoever loses it loses his religion. We ask Allah for safety. And the Prophet (peace and blessings be upon him), when he mentioned prayer one day, said: And these are the leaders of the disbelievers and the most wicked of the disbelievers. So he (peace and blessings be upon him) made it clear that whoever neglects prayer will be gathered with these disbelievers. We ask Allah for safety. So the point is that it is obligatory for you and for the mother to advise, and you have exerted effort in advising. And the mother must exert effort in advising, and after that, boycotting is necessary and declaring hatred for him is necessary, so that he knows that you both hate him for the sake of Allah and that you both boycott him in this matter. Perhaps Allah will guide him and bestow upon him repentance. There is no harm in continuing to advise him from time to time by speech, by telephone, by telegram, by writing, or the like. There is no harm in the believer continuing to advise, but with hatred for the sake of Allah and with boycotting for the sake of Allah, as Allah (Glorified and Exalted is He) said: [Al-Mumtahanah: 4]. So abandoning prayer is disbelief and misguidance. We ask Allah for safety. We ask Allah for his guidance, and we ask Allah to help you and the mother in all good, and to make your advice beneficial, and to accept your supplications for him until Allah guides him. Yes.
