think about this
And to Allah belongs the dominion of the heavens and the earth, and Allah has power over all things. (189) Verily! In the creation of the heavens and the earth, and in the alternation of night and day, there are indeed signs for men of understanding. (190) Those who remember Allah (always, and in prayers) standing, sitting, and lying down on their sides, and think deeply about the creation of the heavens and the earth, (saying): "Our Lord! You have not created (all) this without purpose, glory to You! (Exalted be You above all that they associate with You as partners). Give us salvation from the torment of the Fire. (191) (Ali Imran)
we have eyes and they do their function: see
we have ears and they do their function: hear
we have a brain and it does its function: think
...
we see all things around us and all of them have a function... so the question is:
Does the man have a function in this worldly life?! If we do not have a function here which would be the difference between us and animals?! Is our life just 10, 30, 50, 100 0r 120 years and that's all... all this generations that have died they died and that's all?!
Nobody would be shure that what's around us is just a pure case...
we have never found a lunch or a dinner ready at home prepared from no-one (I would like to find it but I know I have to cook, and I have to work to get the money) nothing comes at me staying at home...
"Our Lord! You have not created (all) this without purpose, glory to You! (Exalted be You above all that they associate with You as partners). Give us salvation from the torment of the Fire.
