‘Ā’ishah (may Allah be pleased with her) reported: While the Messenger of Allah (may Allah’s peace and blessings be upon him) was eating food with six of his Companions, a Bedouin came in and ate it up in two morsels. Thereupon, the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "If only he had mentioned the name of Allah, it would have been enough for all of you."
The Prophet (may Allah's peace and blessings be upon him) was eating with six of his Companions. Meanwhile, a Bedouin entered and ate with them. He ate the rest of the food in two morsels. Thereupon, the Prophet (may Allah's peace and blessings be upon him) said: “If only he had mentioned the name of Allah, it would have been enough for all of you.” However, this man did not mention the name of Allah and that is why he consumed the remaining food in just two morsels and did not get satisfied. This indicates that failure to mention the name of Allah before eating renders the food bereft of blessing.
