Idris is a Prophet in Islam. He is known in the Bible as Enoch.
In the Quran, he is the grand-father of Nuh (Noah). Idris is credited with learning many useful actions or inventing things which humans now use such as writing, mathematics, astronomy, etc. According to Islamic tradition, his time was one when many people had forgotten God, and the world was thus punished with a drought. However, Idris prayed for them, and it began to rain, ending the drought.
