Authenticity of the Qur'an

   Allah has promised to protect the Qur'an from corruption and adulteration:
   No doubt We have sent down the Qur'an and surely We will guard it (from corruption). (Qur'an, 15:9). 
   Allah has truly fulfilled His Promise and for more than fourteen hundred years, not a single word or even letter has been changed. The Qur'an exists in its original Arabic text and not even mixed with the words of Prophet Muhammed (pbuh). It is purely and completely the Word of Allah.
   No honest scholar, Muslim or non-Muslim has ever raised any doubt about the purity and genuineness of the Qur'an. The Qur'an has been transmitted to us in the most reliable ways. It was written down and learnt by heart by hundreds of people during the life time of Prophet Muhammad (pbuh). One of the copies of the Qur'an which was written few years after the death of Prophet Muhammad (pbuh) is still in existence in Tashkent, Uzbekistan. Furthermore, since the time of the Prophet Muhammad (pbuh), thousands and hundreds of thousands of Muslims have memorized the Qur'an in succession.
