Tafwidh is to assign one’s all affairs to Allah.
Allah may do with one as He desires.
One’s aspiration and hope should be on none besides Allah. In addition to employing the means and the methods, the result of all things should be left to Allah.
Tafwid is accquired by immediately reflecting when being confronted with an event which is in conflict with one’s liking that this is from Allah and most assuredly there is wisdom and goodness in it.
In the beginning it will be difficult to acquire this attitude. However, constant reflection facilitates it and then this attitude assumes a natural condition in the Pious (Auliyaa).
