Verily, the number of months with Allâh is twelve months (in a year) according to the law of Allâh since the day He created the heavens and the earth. Of these four (months) are sacred (- Rajab, Muharram, Dhul-Qa`dah and Dhul-Hijjah). That is the established law. Do not do injustice to yourselves (by waging wars) during these (sacred months). And fight the polytheists all together (in your defence) just as they fight you all together. And know that Allâh is indeed with those who become secure against evil.
