Sahih al-Bukhari · Book 34: Sales and Trade · The fat of the dead animal should not be sold
Narrated Ibn `Abbas:
حَدَّثَنَا الْحُمَيْدِيُّ ، حَدَّثَنَا سُفْيَانُ ، حَدَّثَنَا عَمْرُو بْنُ دِينَارٍ ، قَالَ أَخْبَرَنِي طَاوُسٌ ، أَنَّهُ سَمِعَ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ يَقُولُ بَلَغَ عُمَرَ أَنَّ فُلاَنًا بَاعَ خَمْرًا فَقَالَ قَاتَلَ اللَّهُ فُلاَنًا، أَلَمْ يَعْلَمْ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " قَاتَلَ اللَّهُ الْيَهُودَ، حُرِّمَتْ عَلَيْهِمُ الشُّحُومُ فَجَمَلُوهَا فَبَاعُوهَا " .
Once `Umar was informed that a certain man sold alcohol. `Umar said, "May Allah curse him! Doesn't he know that Allah's Messenger (ﷺ) said, 'May Allah curse the Jews, for Allah had forbidden them to eat the fat of animals but they melted it and sold it."
