Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abu Musa Ash'ari (may Allah be pleased with him) that he said: Verily, this Qur'an will be a reward for you and a reminder for you. And it will be a burden upon you. So follow the Qur'an and do not make the Qur'an follow you. Because whoever follows the Qur'an, it will lead him to the gardens of Paradise, and whoever makes the Qur'an follow him, it will seize him by the back of his neck and throw him into Hell.
