The Ruling on Joking and Laughing with the Mushrikin (those who associate partners with Allah) from among the Dhimmi (protected non-Muslims) and those under treaty

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is the ruling on joking and laughing with the mushrikin (those who associate partners with Allah) from among the dhimmi (protected non-Muslims), the musta'min (non-Muslims granted safe conduct), or those under treaty?

Answer:
It is not permissible to be overly familiar with them. You do not harm them, nor do you treat them with harshness, but you do not become overly familiar with them, nor do you laugh with them or joke with them. Yes. Be moderate. Yes.
