All people attack Islam and not other religion. Why it can be?
Normally if everybody attack something or someone, maybe that person or that think have advantage.
Same like this situation.... Why Many missionary always attack Islam because they know that this religion have advantage and growing of number in member are rapidly.
One of example; in USA and Euro states, Many people at that country now more understand what is Islam and make a research about Islam overall through read the Quran, the tradition of Prophet ( Hadith ) and not judge Islam with see what Muslims do. Finally, They Choose Islam as their way of life...
What the secret in this book make so many people want to be a Muslim? Have they found something interesting?
You will know the answer after you read THE QURAN. May Allah bless you and show you the truth in religion. Peace be unto you.
