Umar bin Khattab reported,

We were with the Messenger of Allah ﷺ on one of his journeys when I spoke to him, but he remained silent. I spoke to him again, and he was silent. I spoke to him a third time, and still he gave no reply.So I urged my mount forward and moved away, saying to myself, "May your mother lose you, son of Khattab. You pressed the Messenger of Allah ﷺ three times, and each time he did not answer you. How fitting it would be for the Quran to be revealed about you."It was not long before I heard someone calling out to me. I came to the Messenger of Allah ﷺ, and he said, "Son of Khattab, a surah has been revealed to me tonight that is more beloved to me than anything the sun rises upon, 'Indeed, We have granted you a clear victory' [Fath 48:1]."

عمر بن الخطاب رضي الله عنه يقول

كنا مع رسول الله ﷺ في بعض أسفاره فكلمت رسول الله ﷺ فسكت ثم كلمته فسكت ثم كلمته فسكت فحركت راحلتي فتنحيت وقلت ثكلتك أمك يا ابن الخطاب نزرت رسول الله ﷺ ثلاث مرات كل ذلك لا يكلمك ما أخلقك بأن ينزل فيك قرآن قال فما نشبت أن سمعت صارخا يصرخ بي قال فجئت إلى رسول الله ﷺ فقال يا ابن الخطاب لقد أنزل علي هذه الليلة سورة ما أحب أن لي منها ما طلعت عليه الشمس إنا فتحنا لك فتحا مبينا
