I heard ʿUmar saying, "May Allah Curse so-and-so! Doesn't he know that the Prophet ﷺ said, 'May Allah curse the Jews for, though they were forbidden (to eat) fat, they liquefied it and sold it. "  

سَمِعْتُ عُمَرَ ؓ يَقُولُ قَاتَلَ اللَّهُ فُلاَنًا أَلَمْ يَعْلَمْ أَنَّ النَّبِيَّ ﷺ قَالَ لَعَنَ اللَّهُ الْيَهُودَ حُرِّمَتْ عَلَيْهِمُ الشُّحُومُ فَجَمَّلُوهَا فَبَاعُوهَا  

‘Umar was told ­and on one occasion he said: Umar heard that Samurah was selling alcohol and he said: May Allah destroy Samurah. The Messenger of Allah ﷺ said: ʿMay Allah curse the Jews, He forbade animal fat to them, so they rendered it and sold it.ʿ  

قَاتَلَ اللهُ سَمُرَةَ إِنَّ رَسُولَ اللهِ ﷺ قَالَ لَعَنَ اللهُ الْيَهُودَ حُرِّمَتْ عَلَيْهِمُ الشُّحُومُ فَجَمَلُوهَا فَبَاعُوهَا  

‘Umar was told ­and on one occasion he said: Umar heard that Samurah was selling alcohol and he said: May Allah destroy Samurah. The Messenger of Allah ﷺ said: ʿMay Allah curse the Jews, He forbade animal fat to them, so they rendered it and sold it.ʿ (Using translation from Aḥmad 170)   

عُمَرُ قَاتَلَ اللَّهُ سَمُرَةَ أَلَمْ يَعْلَمْ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَعَنَ اللَّهُ الْيَهُودَ حُرِّمَتْ عَلَيْهِمُ الشُّحُومُ فَجَمَلُوهَا فَبَاعُوهَا»
