To express his gratitude to Allah, he -Yusuf- came out with an invocatory prayer, thus: "O Allah, my Creator, You have graced me with pre-eminence in respect of power, dominion and authority, and You have imparted to me the knowledge of interpreting visions and what they prefigure of future events; You are the Creator, Who generated the heavens and the earth; You are my Tutelary Guardian here and Hereafter." "Disembody my soul, O Allah, impressed with the image of religious and spiritual virtues and join me to those whose deeds had been imprinted with wisdom and piety."
