حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ عَمْرِو بْنِ شُرَحْبِيلَ، عَنْ عَبْدِ اللَّهِ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَىُّ الذَّنْبِ أَعْظَمُ قَالَ ‏"‏ أَنْ تَجْعَلَ لِلَّهِ نِدًّا وَهُوَ خَلَقَكَ ‏"‏ ‏.‏ قَالَ فَقُلْتُ ثُمَّ أَىٌّ قَالَ ‏"‏ أَنْ تَقْتُلَ وَلَدَكَ مَخَافَةَ أَنْ يَأْكُلَ مَعَكَ ‏"‏ ‏.‏ قَالَ قُلْتُ ثُمَّ أَىٌّ قَالَ ‏"‏ أَنْتُزَانِيَ حَلِيلَةَ جَارِكَ ‏"‏ ‏.‏ قَالَ وَأَنْزَلَ اللَّهُ تَعَالَى تَصْدِيقَ قَوْلِ النَّبِيِّ صلى الله عليه وسلم ‏‏{‏ وَالَّذِينَ لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ وَلاَ يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ وَلاَ يَزْنُونَ ‏}‏ الآيَةَ
Translation

Abdullah said: I asked, "O Messenger of Allah, which sin is the greatest?" He replied, "To set up an equal to Allah while He created you." He said: I asked, "Then which?" He replied, "To kill your child out of fear that he might eat along with you." He said: I asked, "Then which?" He replied, "To commit adultery with your neighbor's wife." He said: And Allah, the Exalted, revealed confirmation of the Prophet's, peace and blessings be upon him, statement:

And those who do not invoke with Allah another deity or kill the soul which Allah has forbidden [to be killed], except by right, and do not commit unlawful sexual intercourse
—up to the verse.
