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].
