The greatest weakness of the koran is that it is claimed to be the word of god. therefore if there is a single error the whole book and the religion based upon it, is proven to be wrong. I suspect that very few xtians have read the bible. if they had they would be aware that it is riddled with errors and contradictions. even fewer people have read the koran, (i dont blame them, its even more boring than the bible), it, like the bible contains many errors. here a couple of them. CREATION IN 6 DAYS (an error the koran and bible share) according to these verses in the koran: Sura 7 : 54 (also 10:3; 11:7, and 25:59) 2:29; 23:17; 65:12; 67:3; 71:15 "Indeed your lord is Allah who created the heavens and the earth in 6 days " however in Suras 41 : 9 - 12... we learn that, Say Is it that ye deny Him Who created the earth in TWO Days He set on the (earth), mountains standing firm, high above it, and bestowed blessings on the earth, and measured therein all things to give them nourishment in due proportion, in FOUR Days So He completed them as seven firmaments in TWO Days, now 4 + 2 +2 = 8 DAYS not 6 days. gods math seems to fail him again.... Inheritance Sura 4:11-12 and 4:176 state the Qur'anic inheritance law. "When a man dies, and is leaving behind three daughters, his two parents and his wife, they will receive the respective shares of 2/3 for the 3 daughters together, 1/3 for the parents together [both according to verse 4:11] and 1/8 for the wife [4:12] which adds up to more than the available estate. A second example: A man leaves only his mother, his wife and two sisters, then they receive 1/3 [mother, 4:11], 1/4 [wife, 4:12] and 2/3 [the two sisters, 4:176], which again adds up to 15/12 of the available property. should we buy allah an electronic calculator?
