Abdullah said, "I asked the Messenger of Allah, ﷺ , 'O Messenger of Allah, which sin is the greatest?' He said, 'To associate partners with Allah while He has created you.' I asked, 'Then what?' He said, 'To kill your child out of fear of poverty.' I asked, 'Then what?' He said, 'To commit adultery with your neighbor's wife.' Then he recited this verse, '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. And whoever should do that will meet a penalty.' (Quran 25:68)"
أَخْبَرَنَا عَبْدُ الرَّحْمَنِ بْنُ مُحَمَّدِ بْنِ سَلَامٍ قَالَ حَدَّثَنَا أَبُو أُسَامَةَ عَنْ مَالِكِ بْنِ مِغْوَلٍ قَالَ سَمِعْتُ وَاصِلَ بْنَ حَيَّانَ ذَكَرَ عَنْ أَبِي وَائِلٍ قَالَ
قَالَ عَبْدُ اللهِ سَأَلْتُ رَسُولَ اللهِ ﷺ قُلْتُ يَا رَسُولَ اللهِ أَيُّ ذَنْبٍ أَعْظَمُ؟ قَالَ «أَنْ تَجْعَلَ لِلَّهِ نِدًّا وَهُوَ خَلَقَكَ» قُلْتُ ثُمَّ أَيُّ؟ قَالَ «أَنْ تَقْتُلَ وَلَدَكَ مِنْ أَجْلِ أَنْ يَطْعَمَ مَعَكَ» قُلْتُ ثُمَّ أَيُّ؟ قَالَ «أَنْ تُزَانِيَ حَلِيلَةَ جَارِكَ» ثُمَّ قَرَأَ هَذِهِ الْآيَةَ {وَالَّذِينَ لَا يَدْعُونَ مَعَ اللهِ إِلَهًا آخَرَ} [الفرقان 68] إِلَى قَوْلِهِ {يَلْقَ أَثَامًا} [الفرقان 68]
