[Machine] A man said, "O Messenger of Allah, which sin is the greatest before Allah?" He replied, "To ascribe partners to Allah while He created you." He said, "Then what?" He replied, "To kill your child out of fear that he will eat with you." He said, "Then what?" He replied, "To commit adultery with your neighbor's wife." Then Allah revealed the confirmation of these sins in the Quran, from the 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] until the phrase "in multitudes" [Quran 25:68].
رَجُلٌ يَا رَسُولَ اللهِ أِيُّ الذَّنْبِ أَكْبَرُ عِنْدَ اللهِ؟ قَالَ أَنْ تَدْعُوَ لِلَّهِ نِدًّا وَهُوَ خَلَقَكَ قَالَ ثُمَّ أَيٌّ؟ قَالَ تَقْتُلُ وَلَدَكَ مَخَافَةَ أَنْ يَطْعَمَ مَعَكَ قَالَ ثُمَّ أَيٌّ؟ قَالَ أَنْ تُزَانِيَ حَلِيلَةَ جَارِكَ فَأَنْزَلَ اللهُ تَصْدِيقَهَا {وَالَّذِينَ لَا يَدْعُونَ مَعَ اللهِ إِلَهًا آخَرَ وَلَا يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللهُ إِلَّا بِالْحَقِّ وَلَا يَزْنُونَ} [الفرقان 68] إِلَى قَوْلِهِ {أَثَامًا} [الفرقان 68]
