Ibn 'Abbas (May Allah be pleased with them) reported:
While Jibril (Gabriel) was sitting with the Messenger of Allah ﷺ, he heard a sound above him. He lifted his head, and said: "This is a gate which has been opened in heaven today. It was never opened before." Then an angel descended through it, he said: "This is an angel who has come down to earth. He never came down before." He sent greetings and said: "Rejoice with two lights given to you. Such lights were not given to any Prophet before you. These (lights) are: Fatihah-til-Kitab (Surat Al-Fatihah), and the concluding Ayat of Surat Al-Baqarah. You will never recite a word from them without being given the blessings it contain s."

[Muslim].

-وعن ابن عباس رضي الله عنهما قال: بينما جبريل عليه السلام قاعد عند النبي ﷺ سمع نقيضًا من فوقه، فرفع رأسه فقال: "هذا باب من السماء فتح اليوم ولم 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 تقرأ بحرف منها إلا أعطيته" ((رواه مسلم)).النقيض: الصوت.
