Islam is the divine religion which teaches peace as Islam means peace, It also means "peace acquired by submitting will to Almighty Allah". There is a differce between a Muslim and Islam. A Muslim may not follow Islam properly as per the teachings, it does not mean Islam is a bad religion. Today Islam is increasing at a fast rate all over the world, why ? If you read about Islam, I am sure you will clear all doubts about Islam. Quran is the last and final revelations of Almighty Allah and there is not a single verse in Quran which contradicts. Today if we burn all religious scriptures but still we can have Quran as there are millions of Muslims who can recite the Quran with their memory. This is how Allah protects its revelations. If all Muslims in this world follow the path of Islam, there will not be a single person who will dare to say anything about Islam. We muslims have forgot our history and teachings of Islam and involved only in worldly affairs and that's the reason all this punishments. All Muslims brothers, pls wake up and hold the rope of one Allah and spread the message of Prophet Mohammed (pbuh) that this is no God but one Allah and Prophet Mohammed is the messenger of Allah. Insha Allah, we will have success in this world and life Hereafter.
