What is the ruling on someone who imagined naming a newborn Hamza and then smiled, thinking that the Companion Hamza's name is amusing, and what is the ruling on his wife in this matter, and what is the solution and treatment for obsessive-compulsive disorder (OCD) that may afflict a person as a result of this?

It appears the questioner is suffering from obsessive thoughts (waswasah) concerning the issue of mockery. He should discard these thoughts and not indulge them, for waswasah is a severe illness, and indulging it leads to confusion, pathological doubt, distress, and legal hardship. The wife remains a wife, and the solution to the problem is found in the aforementioned fatwas.
