CORRECTION: Christianity is the world's largest religion.
More and more Christians are leaving the church to become atheist today. A vast majority has never visited the church. So as per active believers, Islam is the largest religion of the world.
By the way, what do you know about friends? Its your basic Islamic teaching that a true Muslim should never be friends with "Yahood o Nasara" (Jews and Christians)
Here you prove your ignorance. Jews and Christians are regarded as 'Ahl-e-Kittab' and therefor a muslim is even allowed to marry a Jew or a Christian. Please do some research before making false claims, you know zilch about Islam.
and that Non - Muslims should be slaughtered. And you are following your teaching by killing Christians, Hindus, Sikhs, Buddhists etc in the so called land of pure. You like secularism in other countries but hate the same in Pakistan.
Islam is a religion of peace if followed by the Book. It doesn't encourage killing of innocent people. It even teaches you to respect other religions.
So kindly donot misquote or take things out of context from the Holy Quran to justify your false propaganda.
Do you think that Bible can not be misquoted?
Let me show you how evil the Bible becomes if you take the following out of context and blame the Christian God for the wars the ancient Israelites fought:
The LORD is a man of war; LORD is his name
Exodus 15:3 - King James Bible
More interesting is the era of Saul when God 'ordered' killings of Philitines:
God forced the Philistines to kill each other
After helping Jonathan with his first slaughter (which wasn't really his first, but Oh well), God took over the killing himself. He didn't have much choice if he wanted to get the killing done, because there were only two swords in all Israel at the time, Jonathan's and Saul's. And it's hard to kill Philistines with only sticks and stones.
So it came to pass in the day of battle, that there was neither sword nor spear found in the hand of any of the people that were with Saul and Jonathan: but with Saul and with Jonathan his son was there found. 1 Samuel 13:22
But God had a plan. He'd force the Philistines to kill each other (and throw in an earthquake for dramatic effect).
And there was trembling ... and the earth quaked: so it was a very great trembling. ...
The multitude melted away, and they went on beating down one another... Every man's sword was against his fellow. 1 Samuel 14:15-20
After the Philistines killed each other, the Israelites must have gathered up their swords and spears, because by the end of the same chapter Saul is fighting everybody at once, "vexing" them all.
So Saul ... fought against all his enemies on every side, against Moab, and against the children of Ammon, and against Edom, and against the kings of Zobah, and against the Philistines: and whithersoever he turned himself, he vexed them. And he gathered an host, and smote the Amalekites, and delivered Israel out of the hands of them that spoiled them. 1 Samuel 14:47-48
