Hadith 192
حَدَّثَنَا أَبُو بَكْرٍ مُحَمَّدُ بْنُ أَبَانَ قَالَ: حَدَّثَنَا وَكِيعٌ، عَنْ هِشَامٍ الدَّسْتُوائِيِّ، عَنْ بُدَيْلِ بْنِ مَيْسَرَةَ الْعُقَيْلِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ عُبَيْدِ بْنِ عُمَيْرٍ، عَنْ أُمِّ كُلْثُومٍ، عَنْ عَائِشَةَ، قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَأْكُلُ الطَّعَامَ فِي سِتَّةٍ مِنْ أَصْحَابِهِ فَجَاءَ أَعْرَابِيٌّ فَأَكَلَهُ بِلُقْمَتَيْنِ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «لَوْ سَمَّى لَكَفَاكُمْ»
It is narrated from Umm al-Mu'minin Sayyida Aisha Siddiqa (may Allah be pleased with her), she says that the Noble Prophet (peace and blessings be upon him) was eating food with his six companions (may Allah be pleased with them all) when a Bedouin (villager) came and ate (the food that was present) in two bites. So the Messenger of Allah (peace and blessings be upon him) said: "If this Bedouin had recited 'Bismillah' at the beginning, this food would have sufficed for all of you."
