It comes from the Qur'an chapter 53, An-Najm (The Star), verses 10-18 and alludes to Muhammad(SAW)'s night journey from Mecca to Jerusalem and then through Heaven. "The Lote Tree of the farthest boundary," as it is called, is believed to be the farthest anyone can travel in Heaven in their approach to Allah; beyond this none can pass. The following are the Quranic verses from which this term is derived (Quran 53:10–18):
10 So did Allah convey the inspiration to His Servant what He (meant) to convey.
11 The heart in no way falsified that which he saw.
12 Will ye then dispute with him concerning what he saw?
13 For indeed he saw him at a second descent,
14 Near the Lote-tree beyond which none may pass:
15 Near it is the Garden of Abode.
16 Behold, the Lote-tree was shrouded (in mystery unspeakable!)
17 (His) sight never swerved, nor did it go wrong!
18 For truly did he see, of the Signs of his Lord, the Greatest!
