Who invoked this supplication?

السلام عليكم ورحمة الله وبركاتة        

ﺑِﺴْـــــــﻢِﷲِﺍﻟﺮَّﺣْﻤَﻦِﺍلرَّﺣِﻴﻢ

Answer:

This is the supplication of Yusuf (AS) which he recited when Allah gathered all his brothers and parents in Egypt.

Explanation: 

Allah saved Yusuf (AS) from his jealous brothers. To get the full attention of the father, they threw him in the well. He was brought to Egypt by a caravan, which sold him to the Aziz of Egypt for a meager price. Allahuthala taught him wisdom. He was gifted with the talent of explanation of the dreams. 

Allah resqued him from cunning women, put him in prison. He was set free from the prison after several years due to explanation of King's dream. The king raised him  to be incharge of grainary. Allah Subhanahuthala brought back to him his brothers twice. He was not only generous with his brothers but forgave them all. He raised his parents to throne. They all prostrated him, as it was the custom of that time.

Thus Allah made his dream true. As he saw sun, moon and the eleven stars prostrating him in his dream during his boyhood i.e. his parents and eleven brothers prostrating him.

At that time he prayed:

 رَبِّ قَدۡ ءَاتَيۡتَنِي مِنَ ٱلۡمُلۡكِ وَعَلَّمۡتَنِي مِن تَأۡوِيلِ ٱلۡأَحَادِيثِۚ  فَاطِرَ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِ أَنتَ وَلِيِّۦ فِي ٱلدُّنۡيَا وَٱلۡأٓخِرَةِۖ تَوَفَّنِي مُسۡلِمٗا وَأَلۡحِقۡنِي بِٱلصَّـٰلِحِينَ

My Lord, You have given me [something] of sovereignty and taught me of the interpretation of dreams. Creator of the heavens and earth, You are my protector in this world and in the Hereafter. Cause me to die a Muslim and join me with the righteous.”

We must also recite this dua’a  particularly after coming out safe from all the difficulties and after attaining success in the work.
