Questions on the Explanation of the Book of Nullifiers of Islam

Question:
Is it permissible to sit with those who mock the scholars, even if it is in jest to be friendly with them or to make them laugh?

Answer:
Did we not tell you that it is not permissible to sit with these people? If you sit with them, your ruling is the same as theirs: whether you are like them in disbelief or like them in sin and disobedience. It is not permissible to sit in gatherings of sins in general; it is not permissible to sit in gatherings of sins and what is wrong in general, except for the purpose of disapproval and attempting to remove these sins and this wrong. As for sitting in silence, being at ease, opening one’s heart, and joking, this takes on their ruling and makes one like them.
