Day of Resurrection while the disbelievers will eternally abide in Hellfire. We seek refuge with Allah from that. We seek refuge with Allah from that! The disbelievers will be veiled from seeing their Lord. They will not see Allah (Glorified and Exalted be He) on the Day of Resurrection, because of their disbelief and misguidance.
The disobedient person is in danger; he may enter Hellfire due to his disobedience, but he will not stay in Hellfire eternally. According to the Hadiths Mutawatir (a Hadith reported by a significant number of narrators throughout the chain of narration whose agreement upon a lie is impossible) reported from the Messenger of Allah (peace be upon him) and the Ijma` of Ahlu lSunnah, he will come out of Hellfire and will enter Paradise. This is contrary to the view held by the Khawarij (separatist group that believes committing a major sin amounts to disbelief) and their followers.
Verily, Allâh forgives not that partners should be set up with Him (in worship), but He forgives except that (anything else) to whom He wills
But if they had joined in worship others with Allâh, all that they used to do would have been of no benefit to them.
It is not for the Mushrikûn (polytheists, idolaters, pagans, disbelievers in the Oneness of Allâh), to maintain the Mosques of Allâh (i.e. to pray and worship Allâh therein, to look after their cleanliness and their building,), while they witness against their ownselves of disbelief. The works of such are in vain and in Fire shall they abide.
If a disobedient person does not repent, he is left to the Will of Allah. If Allah wills, He will forgive and pardon him because of his good deeds, Shafa`ah (intercession) of the intercessors, or through His Grace without intercession. If he repents, Allah (Glorified and Exalted be He) will make him join his fellows from the beginning as a Grace and Bounty from Him.
