He addressed them: "I and you used to worship, besides Allah, that which neither benefits nor harms us. It has become clear to me, through the power Allah—Exalted is He—manifested in my own self, that there is no god but Allah, the God of the Children of Israel. Whoever follows me is of me, and we are equals in the truth. Whoever opposes me, I shall strike him with my sword until Allah judges between us. I give you until tonight; answer me when morning comes." He then retired to his house, lay upon his bed, and Allah took his soul.

This indicates the reality of reincarnation (Taqammus) and transmigration (Tanasukh).

It is also mentioned in the book "Ilzam al-Nasib" by Al-Ha'iri: "A king from the kings of Himyar narrated to me that one of the former kings to whom the lands had submitted—who was called Dhu Sarh—was granted kingship in the prime of his youth. He was of good conduct among the people of his kingdom, generous and obeyed. Their reign lasted seven hundred years. He used to go out frequently for hunting and recreation one day, while he was out for recreation, he came upon two snakes fighting: one was white, as if it were a bar of silver, and the other was black, as if it were a piece of coal. The black snake had overcome the white one and was on the verge of killing it.
