Towards Inner Peace

Imām Ibn Taimiyyah, may Allāh have mercy on him, said:

Al-Fuḍail ibn ʿIyāḍ, may Allāh have mercy on him, said, “One who knows people will find inner peace.” He means–and Allāh knows best–that [one should know] that [people] can neither help [us] nor harm [us unless Allāh wills].
