Abu Hurairah reported,

The Prophet ﷺ said, "I will be the master of mankind on the Day of Resurrection..." Then he mentioned the long hadith of intercession, which is recorded in its proper place. In it he said, "I will set out and come beneath the Throne, where I will fall prostrate before my Lord. Then Allah will open up for me, and inspire me with such praises and beautiful words of glorification of Him as He has not opened up for anyone before me..."
