Energizing one's intellect and disposition is not the way to success. The kindness of the Master cannot be achieved without humility. - Ashraf Ali Thanwi

I developed enthusiasm for Dīn - of which tahajjud is one branch.

Lowering oneself, which is called Tawaadhu’ (humilty), is a great and valuable asset. To achieve this quality, many of the servants of Allah abandoned their kingdom and empire. They didn’t care in the least what people thought of them. Surely, humility must then be a much-prized quality so that people gave it preference to it over the entire world!

To assume a task beyond one’s capability is not proper for a Mu’min. The consequence will be failure, disgrace, worry, and shame. Frustration will then overtake one.
