Shaykh ‘Abdullaah ‘Azzaam said:
“It should be everyone’s goal to be abstinent from worldly pleasures and to fight their desires, since it is impossible for the soul to rise and ascend except if it dominates over its desires and whims.
The soul that becomes a prisoner to its desire will never be able to face the enemy on the battlefield. So if you wish to remain travelling upon the path to Allaah, hold yourself back.”
