The station of Tawakkul on Allāh is built upon one having an excellent understanding of Allāh. Yet whoever doesn't learn of His Lord's perfection and greatness, the execution of His supreme will, the comprehensiveness of His power, His full knowledge, the completeness of His will and the execution of His Divine Decree will not be on a proper state as it relates to Tawakkul on Allāh.
So, Tawakkul on Allāh is built upon having an excellent understanding of Allāh. Based upon this, every time the servant's ʾĪmān of Allāh strengthens and his understanding of Allāh becomes correct, his Tawakkul on Allāh strengthens and his resorting to Allāh becomes greater. He entrusts all his affairs to Allāh, and he resorts to Allah in every one of his affairs, interests and needs, both the religious and worldly affairs.
The evidences from the Book of Allāh and the Sunnah of His Prophet (salallahu 'alayhi wa sallam) which order and encourage us to trust in Allāh, clarify the lofty status of doing so and mention the tremendous fruits and praiseworthy benefits reaped by those who have Tawakkul on Allāh concerning their religious and worldly affairs are numerous.
