Hadith 60
repentancemajor-sins
60 - وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ‏ صَلَّى اللهُعَلَيْهِ وَآلِهِ: إِنَّ اللَّهَ عَزَّ وَجَلَّ غافِرُ كُلِّ ذَنبٍ إِلّا مَن أَحدَثَ دِيناً [أو جَحَدَ مَهراً] أَوِ اغتَصَبَ أَجِيراً أَجْرَهُ، أَوْ رَجُلٌ باعَ حُرّاً.
31-60 According to the same documentation, God’s Prophet (S) said, “Indeed the Honorable the Exalted God will forgive all sins except for inventing a religion (or denying one’s wife’s nuptial gift), oppressively not paying someone’s salary whom you hired, or selling a free person.”
