And if a person were given all of the world and what is in it, it would not fill his emptiness.
Ibn Qayyim Al-JawziyyaWhoever desires to purify his heart, then let him prefer Allah to his desires
Ibn Qayyim Al-JawziyyaDoom comes about because of neglecting to evaluate one's self and because of just following one's whims.
Ibn Qayyim Al-JawziyyaThe heart, in its journey to Allah, Majestic is He, is like that of a bird; Love is its head, and fear and hope are its two wings. When the head and two wings are sound, the bird flies gracefully; if the head is severed, the bird dies; if the bird loses one of its wings, it then becomes a target for every hunter or predator.
Ibn Qayyim Al-Jawziyya
