Islam Folklore The Man Who Committed 99 Murders [EPUB ebook] 

There was a man who had heartlessly murdered 99 people, when all of a sudden he felt remorse over what he had done. He asked the people in his town if they knew anyone who was pious enough to get advice from. They recommended to him an ascetic who lived in the mountains. So the man went to this learned person and told him about the past and his wishing to repent for his actions.
