Imaam
Ibn Qayyim al-Jawziyyah said:
Intention
is the head and pillar of any affair, and its foundation and basis upon which
it is built. Indeed, it is the spirit of an action, its leader and its driver.
Action is dependent on it and built upon it; it is sound with his soundness,
and it will be invalid with its invalidity. Through sincere intention, success
is achieved and lack of it brings about disappointment; and the disparity of
levels in this world and the Hereafter is in accordance with it.
