Will Allah answer the prayers of the mother and family to solve their son's problems and ensure his stability, or will Allah punish him for not praying? And is his statement "Allah does not want this for me" considered despair?

Abandoning prayer is one of the greatest sins that deprives a servant of divine success, as it severs the connection between the servant and their Lord. Some scholars have even considered the one who abandons prayer to be a disbeliever. Among the consequences of turning away from the remembrance of Allah are a life of hardship and being raised blind on the Day of Resurrection. Furthermore, thinking about suicide is a grave mistake and one of the greatest major sins. This brother should be advised and warned about the consequences of abandoning prayer, and reminded that Allah accepts the repentance of His servant as long as the soul has not reached the throat. A Muslim should strive to reside in Muslim lands. Supplication is one of the greatest means to achieve what is desired, especially the supplication of parents for their child, which is an answered supplication that is not rejected. Therefore, supplicate for him for guidance, steadfastness, and the preservation of prayer.
