How hard do you have to pray....

[Wyrd of Gawd]

You can pray as little or as much as you want and it won't make a difference. It's down to Allah. If Allah wants to make you strong, you do not need to pray even once.

Quran 3:26 "Say: "O Allah! Lord of Power (And Rule), Thou givest power to whom Thou pleasest, and Thou strippest off power from whom Thou pleasest: Thou enduest with honour whom Thou pleasest, and Thou bringest low whom Thou pleasest: In Thy hand is all good. Verily, over all things Thou hast power."

That verse refers to "power" as in "authority", the word used is mulk which can be translated as kingdom as well. Not that I disagree that God can take power in the other sense from who he wants and give to he wants, but just wanted to correct you on that. 

Power can sometimes refer to authority so maybe that is why they translated there as that?

Why do people have to translate the Bible and the Koran everytime they read them?  If they are such experts then they should publish their own translations as being the correct ones. And who numbered the chapters and verses?
