[Machine] The Jews disputed with the Prophet Muhammad ﷺ and said, "We eat from what we have killed, but you do not eat from what Allah has killed." So Allah revealed, "And do not eat of that upon which the name of Allah has not been mentioned" [Surah Al-An'am 121].  

خَاصَمَتِ الْيَهُودُ النَّبِيَّ ﷺ فَقَالَتْ تَأْكُلُ مِمَّا قَتَلْنَا وَلَا تَأْكُلُ مِمَّا قَتَلَ اللهُ؟ فَأَنْزَلَ اللهُ ﷻ {وَلَا تَأْكُلُوا مِمَّا لَمْ يُذْكَرِ اسْمُ اللهِ عَلَيْهِ } [الأنعام 121]  

explaining the verse "But the evil ones ever inspire their friend to contend with you" They used to say: Do not eat which Allah killed, but eat which you slaughtered. So Allah revealed the verse: "Eat not of (meats) on which Allah's name hath not been pronounced"...to the end of the verse. (Using translation from Abū Dāʾūd 2818)   

عَبَّاسٍ ؓ فِي قَوْلِهِ ﷻ {وَإِنَّ الشَّيَاطِينَ لَيُوحُونَ إِلَى أَوْلِيَائِهِمْ لِيُجَادِلُوكُمْ} [الأنعام 121] قَالُوا يَقُولُونَ مَا ذَبَحَ اللهُ فَلَا تَأْكُلُوهُ وَمَا ذَبَحْتُمْ أَنْتُمْ فَكُلُوهُ فَأَنْزَلَ اللهُ ﷻ {وَلَا تَأْكُلُوا مِمَّا لَمْ يُذْكَرِ اسْمُ اللهِ عَلَيْهِ} [الأنعام 121]
