Umar continued, "I got my camel moving until, when I was in front of the people, I feared that a piece of Qur'an was being sent down about me. It was not long before I heard a crier calling for me, and I said that I feared that a piece of Qur'an had been sent down about me." He continued, "I came to the Messenger of Allah (ﷺ) and said, 'Peace be upon you' to him, and he said, 'A sura has been sent down to me this night that is more beloved to me than anything on which the sun rises.' Then he recited al-Fath (Sura 48).
