In another reliable tradition it is narrated from ‘Ali that a person came to the Holy Prophet and said, “Messenger of Allah, I have seen an amazing thing.” When the Prophet asked him about it he said, “One of my relative was sick and people advised for him water of Ahqaf well that is situated Wadiul Barhoot. I took a bucket and water bag and reached the place. When I tried to draw water I saw a chain like thing coming from sky with a man tied to it. He was saying give me water I am dying of thirst. I raised the bowl towards him but the chain around his neck tightened and took up to the sun. Again I drew out some water and the same scene was enacted. This happened thrice. So I finally tied up the water bag and did not try to give him any water.” The Holy Prophet said, “He was Qabil the son of Adam; who had killed his brother. And the same thing is mentioned in the Qur’an,
“…and those whom they pray to besides Allah give them no answer, but (they are) like one who stretches forth his two hands towards water that it may reach his mouth, but it will not reach it; and the prayer of the unbelievers is only in error.” (13:14)
