tirmidhi:1858bʿĀʾishah

"The Prophet ﷺ was eating food with six of his Companions. A Bedouin came and ate it in two mouthfuls. So the Messenger of Allah ﷺ said: "As for him, had he mentioned (Allah's Name), it would have been enough for all of you."

الترمذي:١٨٥٨bوَبِهَذَا الإِسْنَادِ عَنْ عَائِشَةَ قَالَتْ

كَانَ النَّبِيُّ ﷺ يَأْكُلُ طَعَامًا فِي سِتَّةٍ مِنْ أَصْحَابِهِ فَجَاءَ أَعْرَابِيٌّ فَأَكَلَهُ بِلُقْمَتَيْنِ فَقَالَ رَسُولُ اللَّهِ ﷺ أَمَا إِنَّهُ لَوْ سَمَّى لَكَفَاكُمْ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَأُمُّ كُلْثُومٍ هِيَ بِنْتُ مُحَمَّدِ بْنِ أَبِي بَكْرٍ الصِّدِّيقِ ؓ
