Discussion of tawakkul (reliance upon Allah) and that it should not be placed in anyone but Allah alone, with mention of the evidence.

The Shaykh : Tawakkul (reliance upon Allah) is a form of worship, is it not? Tawakkul (reliance upon Allah) is a form of worship, so a person should not place his reliance in anyone but Allah alone. Allah the Exalted said: Do not rely on a wali (close friend of Allah) whom you claim or assert to be one who fulfills your needs, like those people who go to the grave of so-and-so or the grave of so-and-so and ask him for their needs and seek his help, while he possesses neither benefit nor harm. Whoever places his reliance in other than Allah as an act of worship is a mushrik (one who associates partners with Allah) and a disbeliever; his claim that he is a believer does not benefit him, because he directed a portion of worship to whom? To other than Allah. And whoever directs a portion of worship to other than Allah has committed shirk (associating partners with Allah) with Allah, major shirk, which takes one out of the religion.
For this reason, we recite at least seventeen times a day and night the words of Allah the Exalted: Just as we do not worship anyone but Allah, we do not seek help from anyone but Allah. And He the Exalted said: Some people hang their hearts on the attainment of what is desired and the repelling of what is disliked upon humans, upon the created beings. If this is reliance on the cause while believing that the cause-giver is Allah Mighty and Majestic, then this is a type of minor shirk (associating partners with Allah). But if it is absolute reliance, complete delegation, delegation involving humility and need, then this is major shirk, because it is not permissible, it is not valid except for Allah Mighty and Majestic.
