"When Jibril was with the Messenger of Allah ﷺ, he heard a sound from above like a door opening. Jibril, peace be upon him, looked up toward the sky and said: 'This is a gate in Heaven that has been opened, but it was never opened before." He said: "An Angel came down from it and came to the Prophet ﷺ and said: 'Receive the glad tidings of two lights that have been given to you and were never given to any prophet before you: The Opening of the Book (Al-Fatihah) and the last verses of Surat Al-Baqarah. You will never recite a single letter of them but you will be granted it.'" (Using translation from Nasāʾī 912)   

بَيْنَا رَسُولُ اللهِ ﷺ وَعِنْدَهُ جِبْرِيلُ إِذْ سَمِعَ نَقِيضًا فَوْقَهُ فَرَفَعَ جِبْرِيلُ بَصَرَهُ إِلَى السَّمَاءِ فَقَالَ هَذَا بَابٌ قَدْ فُتِحَ مِنَ السَّمَاءِ مَا فُتِحَ قَطُّ قَالَ فَنَزَلَ مِنْهُ مَلَكٌ فَأَتَى النَّبِيَّ ﷺ فَقَالَ أَبْشِرْ بِنُورَيْنِ قَدْ أُوتِيتَهُمَا لَمْ يُؤْتَهُمَا نَبِيٌّ قَبْلَكَ فَاتِحَةُ الْكِتَابِ وَخَوَاتِيمُ سُورَةِ الْبَقَرَةِ لَنْ تَقْرَأَ حَرَفًا مِنْهَا إِلَّا أَعْطَيْتَهُ
