The believer speaks little and does
a lot, whereas the hypocrite (munâfiq) speaks a lot and does little. When the
believer speaks, it is with wisdom, when he is silent, it is in deep thought,
when he sees, he takes lessons, and when he acts, it is a cure. If this is the
way you are, then you are in the constant worship [of your Lord.]

Nu’aym, Hilyatu Al-Awliyâ` 8:98.
