In this Allah is different to the God of the Bible, "with whom there is no shadow of turning" (James ), who is "the Lord, who changeth not" (Malachi 3:6), whose Word "endureth forever".It basically says -on one hand Allah is firm and unchanging in what he says - but on the other hand if it helps Muhammad's cause or Muhammad's life style, Allah will change his words to suit Muhammad.Muhammad claimed the angel Gabriel transmitted the entire Koran to him from Allah while he was living in the Hira Cave.
Also revealing is the report by Al Waqidi that Muhammad had such an aversion to the form of the cross that he would break everything brought into the house with a shape of the cross on it (Nehls 19). The exodus to this town, later known as Medina is known by Muslims as the "hijra". the Meccans were defeated by Muhammad's forces, and the Muslims returned to Mecca and cleansed the "kaba" of all its idols.Muhammad's solution was the doctrine of abrogation - the idea that Allah, through Muhammad, can change his mind about anything at anytime and Muslims have to shut up and obey: Furthermore, this Muslim doctrine of abrogation extends so far as to dismiss all previous revelation, given in the Jewish-Christian Bibles.Thus Muslims see no problem in that the Qur'an has re-written biblical history with stories and historical accounts that contradict the Bible.Henceforth Muhammad and his Allah stopped the practice of facing Jerusalem and ordered all prayers to henceforth be said while facing in the direction of Mecca.Yusuf Ali points out in footnote 141, commenting on Surah 2, Muhammad chose Jerusalem for this purpose, but later on, when they proved stubborn in rejecting his apostleship, he came up with a complete change in the direction of prayer; that is, towards Mecca rather than Jerusalem.Apparently then, the Qur'an teaches that some verses that Allah has brought down have been abrogated - that is, they are no longer binding or applicable.Apparently, Allah changed his mind about some of the verses he gave through his prophet.When Muhammad began to preach his new religion in 610 A. The Meccans attacked the Medinans several times, but the Medinans always managed to drive them off. Muhammad continued to rule Medina, where he died in 632 A. Muslims should be reminded of Muhammad's own humanity, fickleness and unworthiness.Muhammad was extremely close to Jews in the beginning of his campaigns of rape, plunder, and murder.See Surahs 6 above, and also 87:6-7, and The doctrine arose from a practical dilemma.Muhammad wanted to marry his daughter in law, but he had already "revealed" the suras that prohibit Muslims from marrying their daughters in law.
