Allah has praised Idris (peace be upon Him), describing him as being a prophet and truthful: "Mention in the Book (Qur’an) Idris (Peace be upon Him). Verily! He was a man of truth (and) a prophet. We raised him to a high station". Qur’an.Surah Maryam 19:56-57
Idris (Peace be upon Him) was born and raised in Babylon following the teachings and religion of Prophet Adam (Peace be upon Him) and his son Seth (Peace be upon Him). Idris (Peace be upon Him) was the 5th generation of the Prophet Adam (Peace be upon Him).
He (Peace be upon Him) called the people back to his forefathers religion, but only a few listened to him, while the majority turned away. Prophet Idris (Peace be upon Him) and his followers left Babylon for Egypt. There he carried on his mission, calling people to what is just and fair, teaching them certain prayers and instructing them to fast on certain days and to give a portion of their wealth to the poor.
He (Peace be upon Him) was the first of the Children of Adam to be given prophet hood after Adam (Peace be upon Him) and Seth (Peace be upon Him). It is reported that he was the 1st to invent the basic form of writing. The first person to write was Prophet Idris. Sahih Al Bukhari Vol 6:480.
Idris (Peace be upon Him) was the first person to write letters using pen. Tafsir ibn Kathir, The Story of Nuh and His People. Some of his wise sayings are: "Happy is he who looks at his own deeds and appoints them as pleaders to his Lord.""None can show better gratitude for Allah’s favors than he who shares them with others.""Do not envy people for what they have as they will only enjoy it for a short while.""He who indulges in excess will not benefit from it.""The real joy of life is to have wisdom."
He (Peace be upon Him) is also mentioned in the hadith of Sahih Al Bukhari Vol 5:227, during the night journey Prophet Muhammad (May allah honor him and grant Him peace) met Him on the fourth heaven (sky).
