Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) narrates: We were with the Messenger of Allah (peace and blessings be upon him) at al-Juhfah, when he (peace and blessings be upon him) came out to us and said: "Do you not bear witness that there is no god but Allah, that I am the Messenger of Allah, and that the Qur'an has come from Allah?" We said: Of course. He (peace and blessings be upon him) said: "Then rejoice, for one end of this Qur'an is in the Hand of Allah and one end is in your hands. Hold fast to it, and you will never be destroyed after it."
