حَدَّثَنَا حَسَنُ بْنُ الرَّبِيعِ وَأَحْمَدُ بْنُ جَوَّاسٍ الْحَنَفِىُّ قَالاَ حَدَّثَنَا أَبُو الأَحْوَصِ عَنْ عَمَّارِ بْنِ رُزَيْقٍ عَنْ عَبْدِ اللَّهِ بْنِ عِيسَى عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنِ ابْنِ عَبَّاسٍ قَالَ بَيْنَمَا جِبْرِيلُ قَاعِدٌ عِنْدَ النَّبِىِّ -صلى الله عليه وسلم- سَمِعَ نَقِيضًا مِنْ فَوْقِهِ فَرَفَعَ رَأْسَهُ فَقَالَ هَذَا بَابٌ مِنَ السَّمَاءِ فُتِحَ الْيَوْمَ لَمْ يُفْتَحْ قَطُّ إِلاَّ الْيَوْمَ فَنَزَلَ مِنْهُ مَلَكٌ فَقَالَ هَذَا مَلَكٌ نَزَلَ إِلَى الأَرْضِ لَمْ يَنْزِلْ قَطُّ إِلاَّ الْيَوْمَ فَسَلَّمَ وَقَالَ أَبْشِرْ بِنُورَيْنِ أُوتِيتَهُمَا لَمْ يُؤْتَهُمَا نَبِىٌّ قَبْلَكَ فَاتِحَةُ الْكِتَابِ وَخَوَاتِيمُ سُورَةِ الْبَقَرَةِ لَنْ تَقْرَأَ بِحَرْفٍ مِنْهُمَا إِلاَّ أُعْطِيتَهُ.

It was narrated that Ibn 'Abbas said: "While Jibril was sitting with the Prophet (s.a.w), he heard a creaking sound from above him. He raised his head and said: 'This is a door in heaven that has been opened today, and it has never been opened before today.' An Angel came down from it and he said: 'This is an Angel who has come down to earth, and he has never come down before today.' He greeted him and said: 'Glad tidings of two lights that have not been given to any Prophet before you: The Opening of the Book and the closing verses of Surat Al-Baqarah. You will never recite one letter of them but you will be given (reward)."'
