Although Khidr is not mentioned in the Quran, Muslim exegetes identify him as the "servant of God" mentioned in Q 18:65. The story of Moses and Khidr is widespread in Muslim and Jewish stories of the medieval period.
Khidr is also associated with immortality and fertility. These are also attributes given to Elijah who is mentioned in the Quran. It is also reported that Elijah and Khidr meet every uear during the month of Ramadan in Jerusalem, that they perform the Pilgrimage together every year, and that they drink from Zamzam enough to keep them until the next year. It is also said that they meet in Arafat each year.
