from Zaid bin Aslam, from his father who said: "I heard 'Umar bin Al-Khattab [may Allah be pleased with him] saying: 'We were with the Messenger of Allah ﷺ during one of his journeys when I said something to him but he was silent. Then I said something again but he was silent. I quickened my pace of mount to go to the other wise. I said: "May your mother lose you O Ibn Al-Khattab! You pestered the Messenger of Allah ﷺ three times, each time he did not reply to you! You deserve that something be revealed about you in the Qur'an.'" He ('Umar) said: "It was not long before I heard a voice calling me.' So I came to the Messenger of Allah ﷺ and he said: "O Ibn Al-Khattab! A Surah was revealed to me last night which is dearer to me than what the sun rises upon: Verily, We have given you a manifest victory (48:1).'"
سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ ؓ يَقُولُ كُنَّا مَعَ رَسُولِ اللَّهِ ﷺ فِي بَعْضِ أَسْفَارِهِ فَكَلَّمْتُ رَسُولَ اللَّهِ ﷺ فَسَكَتَ ثُمَّ كَلَّمْتُهُ فَسَكَتَ ثُمَّ كَلَّمْتُهُ فَسَكَتَ فَحَرَّكْتُ رَاحِلَتِي فَتَنَحَّيْتُ وَقُلْتُ ثَكِلَتْكَ أُمُّكَ يَا ابْنَ الْخَطَّابِ نَزَرْتَ رَسُولَ اللَّهِ ﷺ ثَلاَثَ مَرَّاتٍ كُلُّ ذَلِكَ لاَ يُكَلِّمُكَ مَا أَخْلَقَكَ أَنْ يَنْزِلَ فِيكَ قُرْآنٌ قَالَ فَمَا نَشِبْتُ أَنْ سَمِعْتُ صَارِخًا يَصْرُخُ بِي قَالَ فَجِئْتُ رَسُولَ اللَّهِ ﷺ فَقَالَ يَا ابْنَ الْخَطَّابِ لَقَدْ أُنْزِلَ عَلَىَّ هَذِهِ اللَّيْلَةَ سُورَةٌ مَا أُحِبُّ أَنَّ لِي بِهَا مَا طَلَعَتْ عَلَيْهِ الشَّمْسُ (إنَّا فَتَحْنَا لَكَ فَتْحًا مُبِينًا )
