The book 44 Opportunities for Atheists, Skeptics and Believers reviews 44 opportunities to think about the veracity of the message of the Prophet Muhammad, based solely on the Holy Quran and its Arabic language, and its simple logical and rational references that suit everyone, so this small-sized book comes as an opportunity for atheists and skeptics to determine the authenticity of Islam and its attribution to God Almighty, and for believers to increase their faith in the veracity of their religion.
