Guidance for a father whose adult sons do not pray in congregation

Question:
Honorable Shaykh (may Allah preserve him), I have adult sons who do not maintain the congregational prayer in the mosques. I have made every effort to encourage them to pray in congregation, but to no avail. They say, "We pray at home." I have boycotted them and tried to kick them out of the house, but I could not. What do you advise us to do regarding them, along with your supplications for them and those present for guidance?

Answer:
May Allah reward you with good. Your question indicates that you care and that you have not fallen short, if Allah wills. But continue, keep on enjoining them to pray. Do not leave them by saying, "I am helpless against them," and then abandon them. It is obligatory for you to persist and be patient, and Allah will help you. Do not leave them. If they are independent and can live on their own, if you kick them out of your house they can manage, then let them go. Do not keep them in your house while they are praying with the congregation. Let them be independent of you and manage their own affairs. However, if they have nothing and cannot live on their own, keep them with you as long as they are able to become independent, but with patience and with repeating the command and advice, so that perhaps Allah may guide them. Yes.
