﴿ إِنَّ عِدَّةَ ٱلشُّهُورِ عِندَ ٱللَّهِ ٱثْنَا عَشَرَ شَهْرًۭا فِى كِتَٰبِ ٱللَّهِ يَوْمَ خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ مِنْهَآ أَرْبَعَةٌ حُرُمٌۭ ۚ ذَٰلِكَ ٱلدِّينُ ٱلْقَيِّمُ ۚ فَلَا تَظْلِمُوا۟ فِيهِنَّ أَنفُسَكُمْ ۚ وَقَٰتِلُوا۟ ٱلْمُشْرِكِينَ كَآفَّةًۭ كَمَا يُقَٰتِلُونَكُمْ كَآفَّةًۭ ۚ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ مَعَ ٱلْمُتَّقِينَ ﴾

“BEHOLD, the number of months, in the sight of God, is twelve months, [laid down] in God's decree on the day when He created the heavens and the earth; [and] out of these, four are sacred: this is the ever-true law [of God]. Do not, then, sin against yourselves with regard to these [months]. And fight against those who ascribe divinity to aught beside God, all together-just as they fight against you, [O believers,] all together -and know that God is with those who are conscious of Him.”

(Lo! the number of the months with Allah) he says: the year is counted by months, i.e. the months of the year in which the poor-due is paid (is twelve months by Allah's ordinance) in the Guarded Tablet (in the day) from the day (that He created the heavens and the earth. Four of them) four of these months (are sacred): Rajab, Dhu'l-Qa'dah, Dhu'l-Hijjah and Muharram: (that is the right religion) that is the right calculation: it neither increases or decreases. (So wrong not) harm not (yourselves) through transgression (in them) in those months; it is also said: in the sacred months. (And wage war on all the idolaters) in the sacred months and in other months (as they are waging war on all of you) all together. (And know) O believers (that Allah is with those who keep their duty (unto Him)) with those who ward off disbelief, idolatry, indecencies, the breaking of treaties and fighting during the sacred months.
