“The Mu’minoon are but a single Brotherhood.” (The Holy Qur’an, 49:10)
....!
You my brother are reading this ayah without proper context. Did you read aya 1-9 to understand what kind of topic is being discussed?
Copy paste of Quran for your political purpose is worse than munafiqs. So don't be a munafiq and read first. and understand first.
In year 2012, and in Pakistan (or any other country), this ayah has to be understood in proper context. Use your own brain brother, do not fall into Mullah and Ayatullah trap.
Otherwise Pakistan will remain the play ground of Sunni terrorists attacking innocent Shias (and Shia terrorists attacking Sunnis where they can).
Country is like your house. You must protect it by protecting its borders.
Even blood brothers put up walls around their houses. Don't they?
Their own kids and wife always takes precedence over the blood relations. Such is the nature of human society. Only monkeys and chimps don't have a concept of walls around the house even though they look like humans, but they are still chimps.
And chimps do not have a concept of national boundary either. Even though all chimps are bound with the some sort of brother hood hood.
Same way you setup walls (some times real and sometimes virtual) around your city, and your country. And you don't let every nathu khaira come in regardless of the fact that he is a Muslim or not.
If your blood brother is burning down his house, or doing something stupid. You won't burn down your kids and wife. Would you?
Same thing applies to countries. A country of your birth or a country of your residence takes precedence over your religious brother. Just like the walls around your house take precedence over your blood brother.
And if your blood brother jumps over your wall, you will shoot him or do whatever you can in order to protect your kids and your wife.
Similarly if your will not let anyone come into your country without permission, or let anyone endanger your country because that's where you are raising your kids and protecting your wife.
So my momin brother, do not over-read into the ayah above. It is a concept that you have to understand in the proper context.
peace to you.
