Narrated `Aisha:
حَدَّثَنِي أَحْمَدُ بْنُ الْمِقْدَامِ الْعِجْلِيُّ ، حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحْمَنِ الطُّفَاوِيُّ ، حَدَّثَنَا هِشَامُ بْنُ عُرْوَةَ ،، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ قَوْمًا، قَالُوا يَا رَسُولَ اللَّهِ، إِنَّ قَوْمًا يَأْتُونَنَا بِاللَّحْمِ لاَ نَدْرِي أَذَكَرُوا اسْمَ اللَّهِ عَلَيْهِ أَمْ لاَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " سَمُّوا اللَّهَ عَلَيْهِ وَكُلُوهُ " .
Some people said, "O Allah's Messenger (ﷺ)! Meat is brought to us by some people and we are not sure whether the name of Allah has been mentioned on it or not (at the time of slaughtering the animals)." Allah's Messenger (ﷺ) said (to them), "Mention the name of Allah and eat it."
