People who have memorised the Qur'aan should be known by the night when people are sleeping and he is awake, and by the morning when people are not fasting but he is, by his sadness when they are happy, by his crying when they are laughing, by his silence when they are slandering, and by his piety and humility when they are arrogant. He who has memorised the Qur'aan should be tearful, sad, wise, patient and calm. He should not be rude, inattentive, loud or cruel.

- Ibn al-Qayyim rahimahullaah.
