Al-Baqarah - 2:194

الشَّهْرُ الْحَرَامُ بِالشَّهْرِ الْحَرَامِ وَالْحُرُمَاتُ قِصَاصٌ فَمَنِ اعْتَدَى عَلَيْكُمْ فَاعْتَدُواْ عَلَيْهِ بِمِثْلِ مَا اعْتَدَى عَلَيْكُمْ وَاتَّقُواْ اللّهَ وَاعْلَمُواْ أَنَّ اللّهَ مَعَ الْمُتَّقِينَ
[2:194]
The Sacred month for the sacred month and all sacred things are (under the law of) retaliation; whoever then acts aggressively against you, inflict injury on him according to the injury he has inflicted on you and be careful (of your duty) to Allah and know that Allah is with those who guard (against evil).
The prohibited month for the prohibited month,- and so for all things prohibited,- there is the law of equality. If then any one transgresses the prohibition against you, Transgress ye likewise against him. But fear Allah, and know that Allah is with those who restrain themselves.
The forbidden month for the forbidden month, and forbidden things in retaliation. And one who attacketh you, attack him in like manner as he attacked you. Observe your duty to Allah, and know that Allah is with those who ward off (evil).
