On Sunday, August 22, 2021, I had a chance to discuss the question of the truthfulness of Prophet Muhammad (sa) with friend from the Jehovah Witness community. The question he posed was as follows: Was it truly the angel Gabriel who spoke to Muhammad (sa)? In essence, we discussed the proofs of the truthfulness of Prophet Muhammad (sa). After my initial remarks, he gave his rebuttal followed by my counter-rebuttal and then questions and comments from the live zoom audience.
