one more clarification to you that every body in saudi arabia is not having oil wells. but no body sleeps hungry there. thanks to islam again. i met so many in usa who have visited KSA and admire just like anything. they say even if you dont earn anything there youwill not sleep hungry. people will share their food with you the moment they see you are hungry and it is meal time. islam has got no substitute. islam is the only hope for this problematic world.
