A woman whose son does not pray, and she has advised him many times and threatened him, so what should she do?

Q: A woman asks: She has a son who does not pray, and she has advised him and threatened him, but he does not care. He is sixteen years old. She says that she advises him, but he mocks her. Sometimes he prays and then goes back to his ways, saying that Satan whispers over his head. Such phrases continue from him. She says, "I am seeking refuge in Allah, and then in you, to save me from what I am in and guide me to the right path. What is to be done for a widow who has no power or strength except in Allah?" Then she seeks your help. May Allah reward you with the best reward for her.

A: This boy who does not persist in prayer: it is obligatory to advise him and direct him to good, to admonish him and warn him of the anger of Allah. Allah, Mighty and Majestic, said regarding the people of the Fire: They said, "We were not of those who used to pray" [Al-Muddaththir: 42-43]. So abandoning prayer is among the greatest causes of entering the Fire, because abandoning it is major shirk. The Prophet (peace and blessings be upon him) said: And he (peace and blessings be upon him) said: .
So prayer has a great status, and it is the pillar of Islam, and it is the distinguishing factor between the Muslim and the disbeliever. It is obligatory for every accountable person, male or female, to perform the prayer at its time. He is commanded to do so before he reaches puberty, so that he becomes accustomed to it and practices it, as the Prophet (peace and blessings be upon him) said: And so it is for girls. As for the one who has reached puberty, it is obligatory for him to pray. If he delays in prayer, he must be asked to repent. If he repents, well and good; otherwise, it is obligatory for the one in authority to kill him, because the matter of prayer is great, and it is the second pillar of the pillars of Islam.
So it is upon you, O sister in Allah, to advise your son, and to strive to direct him to good, and to warn him of the consequences of his bad deed. If he persists, disavow him and ask him to leave you and stay away from you, so that his matter does not harm you, and so that the punishment does not befall him while he is with you. It is obligatory for him to obey your command, and to fear Allah , and to obey the command of His Lord, Exalted is He, and the command of His Messenger (peace and blessings be upon him) in performing the prayer. If he does not do so and persists in his stubbornness and disbelief, then it is obligatory for you to boycott him, to dislike meeting him, and to frown at him with dislike and anger at him, and to report his matter to the one in authority. Along with this, you must order those of your relatives who have influence, such as your father, your elder brother, his uncles, or his maternal uncles, to direct him, advise him, and discipline him if they are able, so that perhaps Allah will guide him through your means. Along with this, make du'a for his rectitude and guidance in your prayer and otherwise, that Allah may guide him, inspire him with rightness, and protect him from the evil of his own self, the evil of Satan, and the company of bad people. May Allah rectify him, and may Allah reward you with good for him, and success is from Allah.
