I have said this before, and I am saying it again: Work in Islam is worship.
And it is Jihad.
That means those who are engaged in doing their daily duties — whatever work it is that they do — it is as if they are in Salaah.
They are face to face with Allah. And Allah is watching over them. And Allah is also watching their every move, and reading their every thought, and monitoring the minutest movements of their eyes.
And if they are waiting for work to arrive, it is as if they are in a mosque waiting for Salaah to begin.
And in Islam those who wait for Salaah to start, their position is the same, and their reward is the same, as those who are actually engaged in the performance of the Salaah.
So, if they are pure and honest in their motives and intentions, and diligent and thorough and conscientious in the work that they do, their reward is Paradise and not merely worldly success in the work that they do.
That is how amazing this system of Islam is: You do your own work and you get Paradise in return for it, in addition to your own usual reward in this world, provided your intentions are good and your effort is the very best you could, make it.
