In the name of Allah, the Most Beneficent, the Most Merciful.
Verbally abusing (including swearing at) the religion is kufr (disbelief) in Allah, the Most Supreme, according to the agreement of the scholars, based on statement of Allah Almighty’s:
“And if they break their oaths after their treaty and defame your religion, then fight the leaders of kufr (disbelief), for indeed, there are no oaths [sacred] to them; [fight them that] they might cease.” [Al-Tawbah 9:12]
So whoever falls into something of that, then he is a kafir (disbeliever) and apostate. Repenting from it is by regreting it and not returning to anything of that.
I ask Allah to protect us from those things which make His wrath binding.
