Ibn Abbas reported: While the Angel Gabriel was sitting with the Prophet, peace and blessings be upon him, he heard a creaking noise above him. Gabriel raised his head and he said, “This is a door of heaven that has been opened today and it has never been opened before today.” Then an angel descended from it, and Gabriel said, “This angel descended to the earth today and he has never descended until today.” The angel greeted him with peace and he said, “Rejoice in two lights you have been given, which were not given to any prophet before you: the opening of the Book, Surat al-Fatihah, and the last verses of Surat al-Baqarah. You will never recite a letter from them but that you will be given.”
