In Islamic traition, the Isra and Mi'raj (Arabic: الإسراء والمعراج, al-’Isrā’ wal-Mi‘rāğ) are the two parts of a journey that Muhammad took in one night, in 621 AD (1 BH). Many Muslims consider it a physical journey but some Islamic scholars consider it a dream. A brief sketch of the story is in verses 1 and 60 of one of the Qur'an chapters (#17: sura al isra), and other details were filled in from the supplemental writings, the hadith.
