Advising a Neighbor Who Abandons Congregational Prayer in Cooperation with the Imam

Question:
He says: A neighbor who lives with me in the same building does not pray in the mosque. The imam of the mosque asked me to advise him and told me that advising him is a matter between us and that it is a responsibility shared by all of us. What is the ruling on sharing the responsibility for my neighbor with the imam? And what is the imam’s obligation toward him?

Answer:
There is no doubt that this is correct: that you are all jointly responsible for advising him and sinful for neglecting it. So you and the imam cooperate. Allah the Exalted said: You are responsible because you are his neighbor, and a neighbor has rights over his neighbor. He is responsible because he is the imam of the mosque, and the imam of the mosque checks on the congregation of his mosque, rebukes, and advises those who are lazy. All of you are sinful if you neglect him and leave him alone, or you are rewarded if you attend to him and do with him what is required.
