The 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-JawziyyaAs you can taste a pot full of food with a spoon likewise someone's tounge can tell you about his heart.
Ibn Qayyim Al-JawziyyaThe heart will rest and feel relief if it is settled with Allah. And it will worry and feel anxious if it is settled with the people.
Ibn Qayyim Al-Jawziyya
