The intelligent person’s tongue is behind his heart

Bismillahir Rahmanir Rahim

In the name of Allah, the Most Beneficent, the Most Merciful

It is reported that Al-Hasan Al-Basrî – Allâh have mercy on him – said:

The intelligent person’s tongue is behind his heart: when he wants to speak, he first thinks. If [his words] will be in his favor, he says them, and if they will be against him, he does not speak. And the ignorant person’s heart is behind his tongue: when he merely thinks of saying something, he says it, whether it is for or against him.

  Has not the time yet come for those who believe that 

their hearts should be humble for the remembrance of Allah 

and what has come down of the truth?
