You didn't understand and I don't think you want to...I didn't quote any Hadith and the verses mentioned as you explained them are off the mark. Yet again, it seems your are not genuinely interested in learning anything; rather, you want to posit your preconceived notions. Like Shad said you're comparing an article of faith to how many times one is supposed to pray. Lastly, by not specifying the exact time of the suns position but mention the stages it allows for parts of the world to figure it differently according to their needs.
Lastly, I don't want to converse with you either considering your attitude and your posting history. You really are not doing anyone a favor. Maybe it's entertaining for you but I can think of far better things than waste your time with a religion and people you are averse to.
