Abu Dharr al-Ghifari told that he asked God's messenger how he knew he was a prophet so that he was quite sure of it, and that he replied, "Two angels came to me, Abu Dharr, when I was at a place in the valley of Mecca, one alighting on the earth and the other remaining between heaven and earth. One of them asked the other if this was the man, and when he replied that I was, he told him to weigh me against a man. This was done and I was the heavier. He told him to weigh me against ten men, and when this was done, I outweighed them. He then told him to weigh me against a hundred men, and when this was done, I outweighed them. He then told him to weigh me against a thousand men, and when this was done, I outweighed them; and it seemed to me as if I were looking at them being scattered over me because of the lightness of the scale. Then one said to the other that if he were to weigh me against my people, I would outweigh them." Darimi transmitted the two traditions.
