Abul `Ala' quoted Samura b. Jundub as follows:We were with the Prophet and were taking turns out of a large bowl from morning till night; ten getting up and ten sitting down. He was asked from what it was being replenished and replied, "What are you wondering at[*]?" "It was being replenished only from here," pointing with his hand to the sky. *Mirqat, 5:476, explains this as being addressed by Samura to Abul `Ala. Tirmidhi and Darimi transmitted it.
