إِنَّ عِدَّةَ ٱلشُّهُورِ عِندَ ٱللَّهِ ٱثْنَا عَشَرَ شَهْرًا فِى كِتَـٰبِ ٱللَّهِ يَوْمَ خَلَقَ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ مِنْهَآ أَرْبَعَةٌ حُرُمٌ ۚ ذَٰلِكَ ٱلدِّينُ ٱلْقَيِّمُ ۚ فَلَا تَظْلِمُوا۟ فِيهِنَّ أَنفُسَكُمْ ۚ وَقَـٰتِلُوا۟ ٱلْمُشْرِكِينَ كَآفَّةً كَمَا يُقَـٰتِلُونَكُمْ كَآفَّةً ۚ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ مَعَ ٱلْمُتَّقِينَ

God decrees that there are twelve months- ordained in God’s Book on the Day when He created the heavens and earth- four months of which are sacred: this is the correct calculation. Do not wrong your souls in these months- though you may fight the idolaters at any time, if they first fight you- remember that God is with those who are mindful of Him.
Verily, the number of months with Allâh is twelve months (in a year), so was it ordained by Allâh on the Day when He created the heavens and the earth; of them four are Sacred (i.e. the 1st, the 7th, the 11th and the 12th months of the Islâmic calendar). That is the right religion, so wrong not yourselves therein, and fight against the Mushrikûn (polytheists, pagans, idolaters, disbelievers in the Oneness of Allâh) collectively as they fight against you collectively. But know that Allâh is with those who are Al-Muttaqûn (the pious - See V.2:2).
