Verily Allah and His Messenger have forbidden the sale of wine, carcass, swine and idols, It was said: Messenger of Allah, you see that the fat of the carcass is used for coating the boats and varnishing the hides and people use it for lighting purposes, whereupon he said: No, it is forbidden, Then Messenger of Allah ﷺ said: May Allah the Exalted and Majestic destroy the Jews; when Allah forbade the use of fat of the carcass for them, they melted it, and then sold it and made use of its price (received from it).
أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ عَامَ الْفَتْحِ وَهُوَ بِمَكَّةَ إِنَّ اللَّهَ وَرَسُولَهُ حَرَّمَ بَيْعَ الْخَمْرِ وَالْمَيْتَةِ وَالْخِنْزِيرِ وَالأَصْنَامِ فَقِيلَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ شُحُومَ الْمَيْتَةِ فَإِنَّهُ يُطْلَى بِهَا السُّفُنُ وَيُدْهَنُ بِهَا الْجُلُودُ وَيَسْتَصْبِحُ بِهَا النَّاسُ فَقَالَ لاَ هُوَ حَرَامٌ ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ عِنْدَ ذَلِكَ قَاتَلَ اللَّهُ الْيَهُودَ إِنَّ اللَّهَ ﷻ لَمَّا حَرَّمَ عَلَيْهِمْ شُحُومَهَا أَجْمَلُوهُ ثُمَّ بَاعُوهُ فَأَكَلُوا ثَمَنَهُ
