بِسْمِ اللَّهِ

Bismillaah

In the Name of Allah. The Messenger of Allah (ﷺ) was eating with his six Companions when a desert Arab came and ate up the food in two mouthfuls. Messenger of Allah (ﷺ) said, "Had he mentioned the Name of Allah, it would have sufficed for all of you." -(The dua is mentioned above)
