Sheikh `Abd al-Rahmân al-`Ajlân, lecturer at the Grand Mosque in Mecca
It is not a sin for a person to store the Qur’ân neatly in a drawer or other suitable place that is lower to the ground.
A Muslim does not intend to derogate Allah’s book by doing what you describe. He is merely placing the Qur’ân in its usual storage place before going to sleep.
However, it may not be a good idea to place other books on top of the Qur’ân on the shelf or wherever you might store it. A Muslim should always hold Allah’s book in high esteem. One way to express this esteem is to avoid placing any other book on top of it.
And Allah knows best.
