"Whosoever of you sees an evil, let him change it with his hand; and if he is not able to do so, then [let him change it] with his TONGUE; and if he is not able to do so, then with his heart — and that is the weakest of faith." - Prophet Muhammad.
It doesn't befit a man with an internet connection,a mobile phone,an adequate understanding of a plethora of subjects to keep such knowledge to himself.-UAM
