Sayyidna Ali bin Abi Talib (May Allah be pleased with him) said: I heard the Messenger of Allah (saws) saying:
(“Allah’s book. In it is news for what happened before you, and information about what comes after you, and judgement for what happens between you. It is the Criterion (between right and wrong) without jest. Whoever among the oppressive abandons it, Allah crushes him, and whoever seeks guidance from other than it, then Allah leaves him to stray. It is the firm rope of Allah, it is the wise remembrance, it is the straight path, and it is the one that the desires can not distort, nor can the tongues twist it, nor can the scholars ever have enough of it, and it shall not become dull from reciting it much, and the amazement of it does not diminish.)
بِالْهَزْلِ (Amusement): The Holy Qur’an is very serious, it is not a thing for amusement, completely true without any false. Due to this you have to respect it in your chest, to glorify it in your heart, only then its listener and reciter would be up-lifted by it.
