The Holy Prophet (sawa) said : When Jibrael took me to the Firmament, he said the Adhaan and Iqamah and requested me to lead the prayer. I asked him, ‘Do you consider me superior to yourself?’ Jibrael said, ‘Of course! Allah has made the prophets (as) superior to the angels and you are the most superior of all the prophets!’Then, when we reached the Hijab al-Noor (the Curtain of Light) Jibrael said,’ You must enter this place alone. I am not permitted to go any further!’I asked him, ‘Are you departing leaving me alone?’ Jibrael replied, ‘If I venture any further all my feathers and hair will get burnt!’
“Then I entered the Nahri-Noor (the River of Light). This is the place where the angels don’t enter. I heard a voice there saying, ‘O Muhammad (as)!’ I said, ‘Labbaik, Ya Rub (At Your beck and call, O Allah!). Allah said, ‘O Muhammad (S)! You are My Creation! I Am your Lord! Worship Me only and depend on Me! You are My Noor that I have sent to the people as My Manifestation. I have created the Heaven for you and your descendents. There are elevated positions for your Vicegerents (as) and great rewards fot their Shi’as!’ I asked, ‘Who are my Vicegerents?’ The voice came, ‘The names of your Vicegerents have been engraved on the Saq al-Arsh (the Shank of the Firmament)’ I looked in that direction and found written in the gold the names of all the Vicegerents (as) starting with the name of ‘Ali (as) and ending with that of Mehdi (a.j.), the Last of the Imams (as).
I asked, ‘O my Allah! Are all these my Vicegerents?’ The voice came, ‘They are all my Aulia who will be MyHujjat (Representatives) for the people after you. I shall keep my Faith and Religion flourishing and thriving in the world through them. The last of these Vicegerents (as), the Qaim, will cull the world of all My enemies and purify it. He will be the sovereign of the East and the West. His sway will be there till the world lasted’”
