The Lote Tree.

As the Hindu tradition, the Lote Tree marks the limit of human knowledge. The Qur'an makes it clear that Muhammad saw only one of signs of God, not God himself, and later mystics emphasised the paradox of the vision, in which Muhammad both saw and did not see the Divine essence. The Sufis depicted Muhammad as a hero, blazing a new trail to God in this experience, which is so close to the experience of other mystics in other widely separated traditions. In the thirteen-century Persian account by the great poet Farid ud-Din Attar, were very close in spirit to John of the Cross, who also stressed the importance of leaving all our human concepts and experience behind, going beyond what the Qur'an called the Lote Tree, the boundary of normal mundane knowledge. Attar shows that Muhammad ultimately had to leave everybody behind: even Gabriel could not accompany the Prophet on the last stage of his journey.
