"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.'"  

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 حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ بُنْدَارٌ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ حَدَّثَنَا سُفْيَانُ عَنْ مَنْصُورٍ وَالأَعْمَشِ عَنْ أَبِي وَائِلٍ عَنْ عَمْرِو بْنِ شُرَحْبِيلَ عَنْ عَبْدِ اللَّهِ عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ  

"I asked the Messenger of Allah ﷺ which sin is the worst.' He said: 'That you make an equal to Allah while it is He who created you, that you kill your child so that he not eat with you - or because of your food, that you commit adultery with your neighbor's wife.'" He said: "And he recited this Ayah: 'And those who invoke not any other god along with Allah, nor kill such life as Allah has forbidden, except for what is required, nor commit illegal sexual intercourse - and whoever does that shall receive punishment. The torment will be doubled for him on the Day of Resurrection, and he will abide therein in disgrace (25:68 & 69).'"  

سَأَلْتُ رَسُولَ اللَّهِ ﷺ أَىُّ الذَّنْبِ أَعْظَمُ قَالَ أَنْ تَجْعَلَ لِلَّهِ نِدًّا وَهُوَ خَلَقَكَ وَأَنْ تَقْتُلَ وَلَدَكَ مِنْ أَجْلِ أَنْ يَأْكُلَ مَعَكَ أَوْ مِنْ طَعَامِكَ وَأَنْ تَزْنِيَ بِحَلِيلَةِ جَارِكَ قَالَ وَتَلاَ هَذِهِ الآيَةَ (والَّذِينَ لاَ يَدْعُونَ مَعَ اللَّهِ إِلَهًا آخَرَ وَلاَ يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلاَّ بِالْحَقِّ وَلاَ يَزْنُونَ وَمَنْ يَفْعَلْ ذَلِكَ يَلْقَ أَثَامًا * يُضَاعَفْ لَهُ الْعَذَابُ يَوْمَ الْقِيَامَةِ وَيَخْلُدْ فِيهِ مُهَانًا )
