“Abu ‘Abd Allah (a.s.), has said that Dawud (David) stayed at the station in ‘Arafat and looked at the people who seemed of great number to him. He then climbed the hill and began to pray. When he completed that act of Hajj, Jibril came to him and said, ‘O Dawud, your Lord asks, “Why did you climb the hill? Did you think that the voice of one who calls Me (prays to Me) may remain hidden from Me?”’ He (Jibril) then took him to the sea near Jaddah. He (Jibril) made him swim underwater for a distance equal to forty mornings on land. At that point there was a rock, which he (Jibril) cut open and inside there was a little worm. He (Jibril) said, ‘O Dawud, your Lord says, “I hear the voice of this worm inside this rock in the depth of this sea, but you thought that the voice of a caller (one who prays to Me) may remain hidden and obscure before Me.’””
