Why Muhammad (pbuh) is the Final Messenger of God

Mr. FOG wrote his first book titled "Why God is my only best friend: A psychological approach". In it, he talked about his personal journey of how he overcame anxiety and depression by putting God as the first priority in his life. In that book, he also talked about unseen scenarios and places such as the "Day of Judgement", "Heaven" and "Hell". In order to provide a supplement to that book, he compiled "Why Muhammad (pbuh) is God's Final Messenger. A linguistic approach has been used because Mr. FOG has always been fascinated by God's challenge to mankind to produce a single chapter like that of the Quran in the Arabic language.
