It is mentioned in reliable traditions that Imam Jaafar as-Sadiq (A.S) said, Dawood (David) arrived for hajj, attended Arafat, saw the huge gathering of people there and went on top of a hill and engaged him in supplication in solitude. When he concluded the hajj rituals, Archangel Gabriel came to him and asked, “Why had you gone to the hill? Your Lord asks did you think that your voice would not reach Him due to the noise of the multitude.” Then Archangel Gabriel took Dawood to Jeddah and therefrom made him reach the bottom of the sea and to the depth of a 40 day journey, on land. Then they reached a rock. They split it and found a worm in it. Archangel Gabriel told Dawood, “Your Lord says, ‘I hear the voice of this little insect in the rock at the bottom of the sea and am not unconcerned of his needs (condition) and you imagined that I might not hear your voice due to the amalgamation of the voices of others!’”
