(47) باب مَا جَاءَ فِي التَّسْمِيَةِ عَلَى الطَّعَامِ
It is narrated with this chain of narration, from 'Aishah who said:
"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."[Abu 'Eisa said:] This Hadith is Hasan Sahih. Umm Kulthum is the daughter of Muhammad bin Abi Bakr As-Siddiq, may Allah be pleased with them.
