It is reported that Al-Fudayl b. ‘Ayyâd – Allâh have mercy on him – said:
The believer speaks little and does alot, 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.]
Abû Nu’aym, Hilyatu Al-Awliyâ` 8:98.
