When the trumpet is blown, Allah will take the souls of even the angels. Angels which sole purpose in life is to execute the commandments of Allah, and while they do that, they worship Allah constantly. They pray, the do zikr, they prostrate. And do you know what will they say when the trumpet is blown and they face death? The prophet SAW told us that the angel will say:
"Exalted are you o our Lord, we have not worshipped you the way you deserve to be worshipped."
Even after what they have done. compared to us, for merely just 30 minutes per day for solat etc.. so why we worship Allah, the primary reason is Allah is worshipped because of who He is, even if Allah did not create me and you and all of the creation, he would be worthy of worship.  May Allah forgive our sins. -NY-
