"Allah and His Messenger have forbidden the sale of wine, dead animals, pigs and idols." It was said: "O messenger of Allah, what do you thing about the fat of the dead animal, for ships are caulked with it, skins are daubed with it and people use it in their lamps." He said: "No, it is Haram." And the Messenger of Allah then said: "My Allah curse the Jews, for when Allah, the Mighty and Sublime, forbade the meat (of dead animals) to them, they melted it down and sold it, and consumed its price."  

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 وَيُدَّهَنُ بِهَا الْجُلُودُ وَيَسْتَصْبِحُ بِهَا النَّاسُ فَقَالَ لاَ هُوَ حَرَامٌ وَقَالَ رَسُولُ اللَّهِ ﷺ عِنْدَ ذَلِكَ قَاتَلَ اللَّهُ الْيَهُودَ إِنَّ اللَّهَ ﷻ لَمَّا حَرَّمَ عَلَيْهِمْ شُحُومَهَا جَمَّلُوهُ ثُمَّ بَاعُوهُ فَأَكَلُوا ثَمَنَهُ
