Abdullah bin Abbas reported,

While Jibreel was sitting with the Prophet ﷺ, he heard a creaking sound from above him. He raised his head and said, "This is a gate of heaven that has been opened today, never having been opened before."Then an angel descended through it, and Jibreel said, "This is an angel who has come down to earth, never having come down before."The angel greeted them and said, "Rejoice in two lights given to you that were never given to any prophet before you, the Opening of the Book and the closing verses of Surah al-Baqarah. You will not recite a single letter from them without being granted what it contains."

Sahih

عن ابن عباس قال

بينما جبريل قاعد عند النبي ﷺ سمع نقيضا من فوقه فرفع رأسه فقال: هذا باب من السماء فتح اليوم، لم يفتح قط إلا اليوم، فنزل منه ملك فقال: هذا ملك نزل إلى الأرض، لم ينزل قط إلا اليوم فسلم وقال: أبشر بنورين أوتيتهما لم يؤتهما نبي قبلك، فاتحة الكتاب، وخواتيم سورة البقرة، لن تقرأها بحرف منها إلا أعطيته.
