What is the ruling on performing Hajj on behalf of one who is negligent in prayer?

Question : Honorable Shaykh! This is an Egyptian questioner who has used the letters A, B, and J as a code for his name. He says: Honorable Shaykh! I want to perform Hajj on behalf of my father. As we know, the one who abandons prayer is a disbeliever. My father would sometimes pray at home and sometimes leave it off. He would pray some of the times at their proper times and leave off some of the times. He died without having performed Hajj. I want to perform Hajj on his behalf. What is required of me? May Allah reward you.

Answer : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, and upon his family and his Companions, and upon those who follow them with excellence until the Day of Judgment. There is no doubt that your father committed a great sin by his negligence in prayer to the extent you mentioned, but that does not reach the level of disbelief because he did not abandon prayer. The texts only came with the declaration of disbelief for the one who abandons prayer, so one who prays and sometimes leaves it off is not a disbeliever. Rather, he has committed a great sin, but he is under the will of Allah the Exalted. Yes.
As for your Hajj on his behalf, there is no harm in performing Hajj for him if he did not perform the obligatory Hajj, on the condition that you have already performed Hajj for yourself. This is because one who has not performed Hajj for himself does not perform Hajj for another. This is based on the hadith of Ibn 'Abbas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) The Prophet (peace and blessings be upon him) asked about Shubrumah? He said: A brother of mine, or he said: A relative of mine. He said: Have you performed Hajj for yourself? He said: No. He said: Perform Hajj for yourself, then perform Hajj for Shubrumah.
