Narrated 'Abdullah:

"I said: 'O Messenger of Allah ﷺ! What is the worst sin?' He said: 'That you make and equal to Allah, while it is He who created you.'" He said: "I said: 'Then what?' He said: 'That you kill your child fearing that he will eat with you.'" He said: "I said: 'Then what?' He said: 'That you commit adultery with your neighbors wife.'"

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا سُفْيَانُ، عَنْ وَاصِلٍ، 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 قُلْتُ ثُمَّ مَاذَا قَالَ " أَنْ تَقْتُلَ وَلَدَكَ خَشْيَةَ أَنْ يَطْعَمَ مَعَكَ " . قَالَ قُلْتُ ثُمَّ مَاذَا قَالَ " أَنْ تَزْنِيَ بِحَلِيلَةِ جَارِكَ " . قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ .
