I said, "O Messenger of Allah ﷺ! Which is the biggest sin?" He said, "To set up rivals to Allah by worshipping others though He alone has created you." I asked, "What is next?" He said, "To kill your child lest it should share your food." I asked, "What is next?" He said, "To commit illegal sexual intercourse with the wife of your neighbor."  

قُلْتُ يَا رَسُولَ اللَّهِ أَىُّ الذَّنْبِ أَعْظَمُ قَالَ أَنْ تَجْعَلَ لِلَّهِ نِدًّا وَهْوَ خَلَقَكَ قُلْتُ ثُمَّ أَىٌّ قَالَ أَنْ تَقْتُلَ وَلَدَكَ مِنْ أَجْلِ أَنْ يَطْعَمَ مَعَكَ قُلْتُ ثُمَّ أَىٌّ قَالَ أَنْ تُزَانِيَ حَلِيلَةَ جَارِكَ قَالَ يَحْيَى وَحَدَّثَنَا سُفْيَانُ حَدَّثَنِي وَاصِلٌ عَنْ أَبِي وَائِلٍ عَنْ عَبْدِ اللَّهِ قُلْتُ يَا رَسُولَ اللَّهِ مِثْلَهُ قَالَ عَمْرٌو فَذَكَرْتُهُ لِعَبْدِ الرَّحْمَنِ وَكَانَ حَدَّثَنَا عَنْ سُفْيَانَ عَنِ الأَعْمَشِ وَمَنْصُورٍ وَوَاصِلٍ عَنْ أَبِي وَائِلٍ عَنْ أَبِي مَيْسَرَةَ قَالَ دَعْهُ دَعْهُ  

I said 'O Messenger of Allah ﷺ! Which sin is the greatest?" He said, "To set up a rival unto Allah, though He Alone created you." I said, "What next?" He said, "To kill your son lest he should share your food with you." I further asked, "What next?" He said, "To commit illegal sexual intercourse with the wife of your neighbor." And then Allah revealed as proof of the statement of the Prophet: 'Those who invoke not with Allah any other god)................. (to end of verse)...' (25.68)  

قُلْتُ يَا رَسُولَ اللَّهِ أَىُّ الذَّنْبِ أَعْظَمُ قَالَ أَنْ تَجْعَلَ لِلَّهِ نِدًّا وَهْوَ خَلَقَكَ ثُمَّ قَالَ أَىُّ قَالَ أَنْ تَقْتُلَ وَلَدَكَ خَشْيَةَ أَنْ يَأْكُلَ مَعَكَ قَالَ ثُمَّ أَىُّ قَالَ أَنْ تُزَانِيَ حَلِيلَةَ جَارِكَ وَأَنْزَلَ اللَّهُ تَصْدِيقَ قَوْلِ النَّبِيِّ ﷺ {وَالَّذِينَ لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ}  

I asked Messenger of Allah ﷺ "What is the biggest sin in the sight of Allah?" He said, "To set up rivals unto Allah though He alone created you." I said, "In fact, that is a tremendous sin," and added, "What next?" He said, "To kill your son being afraid that he may share your food with you." I further asked, "What next?" He said, "To commit illegal sexual intercourse with the wife of your neighbor."
