What is the ruling of Islamic law on one who swore by triple divorce and by the unlawfulness of his religion not to bring something to his son, then regretted it?

According to the majority of scholars, a conditional divorce takes effect upon the fulfillment of the condition. So, if you brought the item that you swore not to bring to your son, then, according to the majority of scholars, a triple divorce has occurred, and your wife becomes unlawful to you until she marries another husband. However, if you intended to threaten or prevent and did not intend divorce, then according to Sheikh al-Islam Ibn Taymiyyah, only an expiation for an oath (kaffarat yamin) is binding upon you. If you intended divorce, then a single divorce is binding upon you. The phrase "علي الحرام من ديني" (Haraam on my religion) is not considered a binding oath, and neither divorce nor expiation results from it. However, uttering it is a heinous sin and a grave abomination, though it does not lead its utterer to disbelief.
