Contentment is the greatest door that one enters to Allah, it is the source of tranquility for the worshiper and paradise on earth. Whoever does not enter it will not enter the Paradise in the Hereafter.
Ibn TaymiyyahThe one who is [truly] imprisoned is the one whose heart is imprisoned from Allah and the captivated one is the one whose desires have enslaved him.
Ibn TaymiyyahWhatever is not done by the permission of Allah will not happen, and what is not done for the sake of Allah will not benefit or remain.
Ibn TaymiyyahMake tawba not just for sins you've committed, but also for obligations you haven't fulfilled.
Ibn Taymiyyah
