Is Prophet Muhammad (pbuh)a messenger of GOD

Iv'e already explaioned how Muhammad could not have been a liar, because he did not have the motives of a liar(fame, glory, money) as I'v explained in round 2. The only other argumnet that u have is that Muhammad(pbuh) was either deluded, possessed or mentally ill Someone who has dealt with mentally ill knows people can be identified by their symptoms. Muhammad displayed no symptom of insanity at any time in his life No friend, wife, or family member suspected or abandoned him due to insanity. As for the effects of revelations on the Prophet, such as perspiration and the likes, it was due to the intensity of the Message which he had to bear and not due to any epileptic fit or instance of insanity... Quite to the contrary, Muhammad preached for a long time and brought a Law unknown in its completeness and sophistication to ancient Arabs. If the prophet was insane, it would have been obvious to those around him at one point in a period of twenty three years. When in history did an insane man preach his message to worship One God for ten years, three of which he and his followers spent in exile, and eventually became the ruler of his lands? Which insane man has ever won the hearts and minds of people who met him and earned the respect of his adversaries? More so, his closest companions, Abu Bakr and Umar were recognized for their abilities, nobility, skills, and finesse. They were willing to sacrifice anything for the religion he brought. On one occasion, Abu Bakr, brought all his material possessions to Muhammad, may the mercy and blessings of God be upon him, and when asked what he left for his family, responded, ï¿½€˜I left for them God and His Messenger!ï¿½€™ Abu Bakr, a merchant by profession, after being elected the ruler of all of Arabs after Muhammad, spent a mere two dirham on himself and his family! Umar became the ruler of Arabia after Abu Bakr and conquered Syria, Egypt, and subdued the Persian and Roman Empires. He was a man known for his scrupulous justice. How can someone suggest these people were following a mentally deranged individual? Micheal H Hart who is also a prominent hsitorian along with 5 other contemnporay carried out categorical studies on who were the 100 most influential people in history. Guess who he put first, no other than Muhammad(pbuh) Micheal Hart was not a muslim so it could not have been biased. this is what he wrote My choice of Muhammad to lead the list of the worldï¿½€™s most influential persons may surprise some readers and may be questioned by others, but he was the only man in history who was supremely successful on both the secular and religious level. ...It is probable that the relative influence of Muhammad on Islam has been larger than the combined influence of Jesus Christ and St. Paul on Christianity. ...It is this unparalleled combination of secular and religious influence which I feel entitles Muhammad to be considered the most influential single figure in human history. does this sound like muhammad (pbuh) was deluded or mentally ill or possessed. and opponent instead of making vague statements you need to debunk my arguments in round 2 first with evidence and then construct your own showing that Muhammad was a liar or deluded. If u cannot the only other option is that Muhammad (pbuh) was telling the truth that he indeed wa a messenger sent by god
