سَبِّحِ اسْمَ رَبِّكَ الأعْلَى
Glorify the Name of your Lord, the Most High.
Ja’far bin Muhammad relates from his father, from his grandfather, who said:
“Indeed, Allah has an angel named Hizqaa’eel who has 18 000 wings – the distance from wing to wing being the distance of a journey of 500 years. A thought occured to him: ‘Is it possible to see the Throne in its entirety?’ So Allah increased his wings with an equal amount, so that he had 36 000 wings – the distance from wing to wing being 500 years. Thereafter, Allah inspired to him: ‘O angel, fly!’ So he flew for 20 000 years and did not reach the top of one of the legs of the Throne. Thereafter, Allah doubled his wings and his strength and commanded him to fly. So he flew for another 30 000 years more and still did not arrive. Then Allah inspired to him: ‘O angel, were you to fly, with your wings and your strength, until the blowing of the Horn – you would never reach the leg of my Throne.’ So the angel said: ‘Glory be to my Lord, the Most High.’ Allah then revealed: ‘Glorify the Name of your Lord, the Most High.'”
