Musannaf Ibn Abi Shaybah 33862 — What Allah the Exalted gave Muhammad

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: While Jibril was sitting with the Messenger of Allah (peace and blessings be upon him), Jibril heard a sound of something breaking above him. He raised his head and said: A gate of heaven has been opened that had never been opened before today. Then an angel came to him and said: Rejoice in two lights that have been given to you and have not been given to anyone before you: Surah Al-Fatihah and the closing verses of Surah Al-Baqarah. You will not recite a letter of them without being given it.
