Hearts become Cooled due to the Qur’aan
Allaah Ta’ala said:
( وإنه لهدى ورحمة للمؤمنين )
《 And truly, it (this Qur’aan) is a guide and a mercy for the believers. 》 [an-Naml: 77]
Shaykh Sa’adi -Rahimuhullaah- said:
‘Meaning that their hearts become cooled due to the Qur’aan. Their worldly and religious matters become corrected.
This is for those (believers) who believe in the Qur’aan and believe it to be truthful. Those who truly accept it, those who turn to it to reflect upon it. Those who ponder over its meanings, so they are the ones who acquire guidance to the straight path and this mercy incorporates happiness, victory and success.’
