[Pooya/Ali Commentary 53:15] In the region of bliss beyond sidratil muntaha the Holy Prophet saw the glory of the kingdom of Allah, and became fully aware of the wisdom governing it. There were wonders both spiritual and sensible but the Holy Prophet, neither dazzled nor confounded, remained firm and self-possessed, engrossed in the unique experience of beholding the glory of the Lord. There was no visual delusion nor any intellectual or emotional disturbance. The arsh or throne (the seat of divine authority) and Allah's presence are figuratively localised in the highest heaven because human knowledge and imagination are unable to understand the dimensionless existence and sway of the eternal Lord of the worlds with the theories of time and space. Verse 255 of al Baqarah: says: "His throne (presence, wisdom and authority) extends over the heavens and the earth (whole universe)". See commentary of Baqarah : 255. In the case of Musa it was but a prefigurament of the divine effulgence on this earth. See commentary of Ta Ha: 10 to 14; Qasas: 30; and also Exodus 3: 1 to 6 in the Old Testament. Through a fire in the bush Allah granted Musa a little manifestation of His glory on the mountain of Sinai. Refer to Araf: 143 for what took place when Musa saw the manifestation of divine glory. In case of the Holy Prophet it was divine glory in its full splendour in the highest heaven which he saw, understood and absorbed as verse 18 confirms.
