Is it Islamically permissible to involuntarily utter the name of Allah and send blessings upon the Prophet (peace be upon him) during ejaculation in a lawful marital bed?

It is unanimously disliked to mention Allah verbally during intercourse, as reported from Ibn Mas'ud and others, but it is permissible to remember Him in one's heart. It is recommended to recite the prescribed remembrances before initiating intercourse. As for what emanates from a man unintentionally or without will during intercourse, there is no blame upon him; for it is considered an error that Allah has forgiven for His Ummah. Nevertheless, one must strive to discipline oneself and not return to such behavior.
