It is a very large Tree beyond the seventh heaven. It is named Sidra-tul-Muntaha (سدرۃ المنتهی) because there terminates at it whatever ascends from the earth and whatever descends undefined including what comes down from God, including waḥyi (divine inspiration) and other things besides. Alternatively, undefined it is the Uttermost Extremity or the very end of something undefined (which is one of the many Arabic words for the word end) for the knowledge of the creatures approaching it, relative, that is, to its Existent Being undefined above the heavens and the earth. So it is al-Muntaha (the Extremity, Boundary) with respect to undefined modes of knowledge (`ulum: علوم) or other things besides. It is an end of the seventh heaven, the boundary where no creation can pass, according to Islamic beliefs. During the Isra and Mi'raj (اسراء والمعراج), Prophet Muhammad ﷺ, being the only one allowed who crossed it (without any angel or any other creation). He travelled with the archangel Gabriel to the Sidra-tul-Muntaha where it is said that Allah assigned the five daily prayers to all humans.
