Is it considered blasphemy and apostasy if a man, while agitated, says: "Did you go to the mother of the mosque?" and then retracts his statement the next day, saying: "I did not mean that?"

It is not known with certainty what the speaker of the phrase, which indicates anger and dissatisfaction, intended. It is an incorrect phrase that should be avoided. Its ruling depends on the intention of its speaker and the object of their anger. If it is free from insulting the mosque and the rituals of Allah, then it has no connection to disbelief.
