Allah has prepared for them a severe Punishment (in the Hereafter). Therefore fear Allah, O ye men of understanding - who have believed!- for Allah hath indeed sent down to you a Message,- At-Talaq 65:10 ⧉
Tafsir:
‘So, fear God, O men of understanding.’ This statement indicates that the fountainhead of piety (taqwa) is the mind. Only by using his wisdom and consciousness does a man achieve that status which is called (taqwa) in the Islamic law.
