The Prophet Muhammad is the noblest in the world, he is very obedient worship and always give examples of good deeds for humanity. All his actions are always protected by God so that is always preserved from bad deeds.
Muhammad is the last prophet and messenger who brought the Qur'an as a torch and a hint of human life that contains wisdom, history, worship, and law. Anyone who is obedient to Allah and to live up to the example of Muhammad, then he will not grief and sorrow, and his life will be safe in this world and in the hereafter.
In essence, Muhammad also was a man who had a habit and feeling like a human being, such as hunger, thirst, and drowsiness. During his lifetime he never lied and cheated, even against enemies though. That is why he is the most precious in the world.
Al Quran was revealed to the prophet Muhammad but Muhammad is not the author and the of the Qur'an. Prophet Muhammad is a umi that can not read and write. Does it make sense if the Qur'an is his creation? Is the situation such that he could put together word by word meaning can be outside, and set up a law without the need to learn?
Will they not, then, meditate upon the Qur’an? Had it been from anyone other than Allah, they would surely have found therein much disagreement. (Quran Sura Annisa:83)
