Surely the number of months with Allah is twelve months in Allah's ordinance since the day when He created the heavens and the earth, of these four being sacred; that is the right reckoning; therefore be not unjust to yourselves regarding them, and fight the polytheists all together as they fight you all together; and know that Allah is with those who guard (against evil).

Or have they associates who have prescribed for them any religion that Allah does not sanction? And were it not for the word of judgment, decision would have certainly been given between them; and surely the unjust shall have a painful punishment.
