Application Of Tawakul
Tawakkul means to make your best effort and then be content with the results whatever they may be. This is essentially an effort-centric approach, as opposed to a result-centric approach. I’m not sure what your question is in regards to the ayah you quoted.
So if I’m correct in saying tawakul will not change how you act at all- but how you view results. Is the above ayah saying the same thing? Is it saying don’t worry about what hapoens it will only happen with the will of Allah
