Islamic Calendar:-
9: 36 The number of months in the sight of Allah is twelve (in a year) so ordained by Him the day He created the heavens and the earth; of them four are sacred; that is the straight usage. So wrong not yourselves therein and fight the pagans all together as they fight you all together. But know that Allah is with those who restrain themselves.
*** The FOUR Sacred Months were sacred during the PAGAN period but were 'Islamized' by Muhammad and shamelessly incorporated in his new cult belief system***
9: 37 Verily the transposing (of a prohibited month) is an addition to unbelief: the unbelievers are led to wrong thereby: for they make it lawful one year and forbidden another year in order to adjust the number of months forbidden by Allah and make such forbidden ones lawful. The evil of their course seems pleasing to them. But Allah guideth not those who reject faith.

*** Muhammad's tampering with the calendar caused enormous problems for his followers in counting the years since he did not allow for the intercalary days to be inserted.
Most important of all is the interpreter's utter contempt for the truth and the 'Muslim' historical record which shows clearly that it was Muhammad and his followers who broke and flouted every sacred rule that the Arabs held including the AMBUSHING of caravans and conducting warfare in the Prohibited Months ***
