The more you dig up from the muslim textsources, on the character of Muhammad, the more filth you find. Speaking of digging, have you been introduced to Muhammad the graverobber?
Narrated Abdullah ibn Amr ibn al-‘As: When we went out along with the Apostle of Allah (peace_be_upon_him) to at-Ta’if we passed a grave. I heard the Apostle of Allah (peace_be_upon_him) say: This is the grave of Abu Righal. He was in this sacred mosque (sanctuary) protecting himself (from punishment). When he came out, he suffered the same punishment which his people suffered at this place, and he was buried in it. The sign of it is that a golden bough was buried with him. If you dig it out, you will find it with him. The people hastened to it and took out the bough. (Abu Dawud/ Book 13/ hadith 3082)
