Abu 'l-Darda’ encountered a man who had withdrawn from humanity and lived completely by himself. "God be implored," he exclaimed, "on your behalf! Whatever induced you to withdraw from human society?"
"My terror lest my faith be stripped from me, without me knowing," said the man.
Abu 'l-Darda’ said, "In all the host of Muslims, are there a hundred who fear like you?" He went on [repeating the question, each time] lowering the number until he got to ten. At this, the man said:
"There is one man, in Syria." That man was Shurahbil ibn al-Simt.
