The Book of Military Expeditions – Rulings Regarding apostates
Those [sayings / actions / beliefs] which necessitate [the ruling of] kufr [upon a person]
عن ابْنِ سَلَّامٍ رَحِمَهُ اللَّهُ تَعَالَى في من يقول لَا أَعْلَمُ أَنَّ الْيَهُودَ وَالنَّصَارَى إذَا بُعِثُوا هل يُعَذَّبُونَ بِالنَّارِ أَفْتَى جَمِيعُ مَشَايِخِنَا وَمَشَايِخُ بَلْخٍ بِأَنَّهُ يَكْفُر

It is narrated by Ibn Sallaam, may Allah Ta’ala have mercy on him – On the one who says, “I don’t know if the jews and christians will be tormented by the inferno upon being raised [on the day of judgment]”, ALL our shaykhs and their senior shaykhs have ruled that he has disbelieved.
How can it not be ruled so, for it is a denial of the Quran! Allah says in the Quran:
إِنَّ الَّذِينَ كَفَرُوا مِنْ أَهْلِ الْكِتَابِ وَالْمُشْرِكِينَ فِي نَارِ جَهَنَّمَ خَالِدِينَ فِيهَا ۚ أُولَٰئِكَ هُمْ شَرُّ الْبَرِيَّةِ
Translation of meaning: Indeed those who disbelieve [in Allah and His Messenger], from the people of the book, and the polytheists/pagans, they shall be in the fire of hell, therein to abide for ever; they are the worst of creation. [Holy Quran 98:6]
Other disbelievers are only more severe disbelievers than christians and jews as explained by the scholars.
Apostasy rulings do not apply to new converts who are starting to learn Islam and/or do not have a Muslim environment to interact with other Muslims and therefore know any better. They apply once they are aware of a matter.
May Allah grant us life as Muslims and deaths as Muslims.
And success isn’t but by His granting.
