Narrated Zaid bin Aslam

My father said, "Allah's Messenger (ﷺ) was proceeding at night on one of his journeys and `Umar bin Al- Khattab was going along with him. `Umar bin Al-Khattab asked him (about something) but Allah's Apostle did not answer him. `Umar asked him again, but he did not answer him. He asked him again (for the third time) but he did not answer him. On that `Umar bin Al-Khattab addressed himself saying, "May your mother be bereaved of you, O `Umar, for you have asked Allah's Messenger (ﷺ) thrice, yet he has not answered you." `Umar said, "Then I made my camel run fast and took it in front of the other Muslims, and I was afraid that something might be revealed in my connection. I had hardly waited for a moment when I heard somebody calling me. I said, 'I was afraid that something might have been revealed about me.' Then I came to Allah's Messenger (ﷺ) and greeted him. He (i.e. the Prophet) said, 'Tonight there has been revealed to me, a Sura which is dearer to me than (all the world) on which the sun rises,' and then he recited: 'Verily! We have granted you (O Muhammad) A manifest victory." (48.1)
