Forgives All Other Than Shirk – Quran 4:116
If you look at the flow of verses [1] , they were talking about munafiqeen (hypocrites) who joined with the cause of mushriks (idolators) who were knowingly engaged in open shirk as their religion and then Quran says that this shirk, the one practiced by idolators of Arab is unforgivable. Therefore, this automatically follows, that it has to be with a conscious knowledge. This is also reflected in God’s punishment under itmam-e-hujjah where people of the book and Idolators of Arab were separated despite the fact their crime was same i.e. rejecting a rasul and insisting on their polytheism, but due to the fact that conditions of perpetrators differ in their manifestation of this shirk, the former were given a comparatively lower punishment. The same can be inferred for what will happen on the day of judgement. This is a crime solely associated with God and God has clarified that it is unforgivable. But the case with haqooq-ul-ibaad is different, it adds an additional party on whom the crime happened, therefore, it leaves open the possibility of forgiveness in this case. But it will all be done in accordance with the laws mentioned clearly by God himself and Justice is an absolute clause in every case. ________________________________________ [1] وَمَن يُشَاقِقِ الرَّسُولَ مِن بَعْدِ مَا تَبَيَّنَ لَهُ الْهُدَى وَيَتَّبِعْ غَيْرَ سَبِيلِ الْمُؤْمِنِينَ نُوَلِّهِ مَا تَوَلَّى وَنُصْلِهِ جَهَنَّمَ وَسَاءتْ مَصِيرًا إِنَّ اللّهَ لاَ يَغْفِرُ أَن يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَلِكَ لِمَن يَشَاء وَمَن يُشْرِكْ بِاللّهِ فَقَدْ ضَلَّ ضَلاَلاً بَعِيدًا [On the other hand], they who oppose the Prophet (sws) even after the path of guidance is fully evident to them , and leaving the path of those who sincerely professed faith in you follow some other path, We will put them on the path on which they themselves went and cast them into Hell. It is a very evil abode. [Thus, this is what happened and leaving the path of faith, they have now joined the Idolaters. Tell them:] God will not forgive associating partners with Him. However, He will forgive [according to His law] lesser [sins] of whomsoever He wants . [So stay away from polytheism] and [remember] he who imputes partners to God has strayed far indeed. (4:115-116)
No mention of of any other parties is there. It simply says all sins.
