What is the ruling on shunning family members who do not pray, especially the father, sister, and her husband, and do good deeds such as prayer and charity become nullified because of this shunning, and why is there a difference of opinion regarding the excommunication of one who abandons prayer out of laziness, despite the existence of prophetic hadiths such as: "The covenant between us and them is prayer, so whoever abandons it has disbelieved," and "Indeed, between a man and disbelief—or polytheism—is the abandonment of prayer"?

Abandoning prayer is one of the gravest sins. It has been said that one who abandons it, even if not out of denial, is an unbeliever. However, others hold that such a person is not an unbeliever but should be disciplined and imprisoned until they pray, citing that the predecessors inherited from and prayed over those who abandoned prayer. Shunning the one who abandons or is negligent in prayer is religiously مطلوب (required), but it is contingent upon the realization of benefit and utility. If shunning yields no benefit, then advice and reminders about the danger of abandoning prayer should continue, along with efforts to persuade the father to be an aid in their guidance. Estrangement between kin without a legitimate religious justification does not prevent the acceptance of righteous deeds, but it does prevent the forgiveness granted on Mondays and Thursdays.
