How can an Arab who has converted to Buddhism avoid being accused of being a "Kafir Harbi" (belligerent disbeliever), and is their practice of Buddhist rituals in front of Muslim and non-Muslim visitors considered "warfare against Islam," especially given the circulation of the Hadith "I bear witness that her blood is permissible" regarding the female apostate?

Religion is the most precious possession of a human being, and attaining the truth in it is the most important pursuit for a rational person, who must have evidence and proofs for the correctness of their belief. It is highly probable that the questioner abandoned Islam and embraced Buddhism due to their ignorance of Islam and their being influenced by those with whom they live. The Messenger of Allah (peace be upon him) forbade companionship with non-believers. Before answering, the questioner is advised to reacquaint themselves with Islam by reading a sincere and impartial interpretation of the Holy Quran, so that they may know that Islam is the true religion and that Buddhism is a myth. The matter is not trivial, for it concerns eternal happiness or misery. As for their question about ways to avoid becoming a belligerent disbeliever, there is no such way, because their abandonment of Islam is considered apostasy. The punishment for an apostate in the sight of Allah is death if they do not repent and return to Islam, for apostasy is more severe than original disbelief, and there is no salvation from death except by returning to Islam. Mere apostasy is considered hostility towards Islam, even if one does not fight Muslims, although one who calls for fighting Islam is more sinful. The fatwa notes that the implementation of Hadd punishments is the prerogative of the ruler or their deputy only.
