The Repentance - 9:36
The number of months in Allah´s Book on the day He created the heavens and the earth is twelve according to Allah. Four of them are sacred. This is the perfect religion; do not wrong yourselves in those months (by fighting). But if the idolaters fight you in a total war, then fight them in a total war. Know that Allah is with the righteous.
The four holy months; months in which war is forbidden for the safety of people:
The Repentance/9:36
The number of months in Allah´s Book on the day He created the heavens and the earth is twelve according to Allah. Four of them are sacred. This is the perfect religion; do not wrong yourselves in those months (by fighting). But if the idolaters fight you in a total war, then fight them in a total war. Know that Allah is with the righteous.
The Cow/2:197
Hajj should be performed in the known months. Whoever has decided to perform Hajj in those months, know that in Hajj there is no sexual intercourse, no evil deeds, and no arguing. Allah knows every good deed you do. When you prepare your provisions for the journey, remember that the best provision is virtue. People of understanding! Listen to me.
The Table Spread/5:97
Allah has made the Ka´bah, the sacred house, the sacred months, the sacrifices and the wreaths marking them, a security for mankind. Know that Allah knows what is in the heavens and the earth. Allah is All-Knowing.
The Repentance/9:2
Travel in the earth for four more months, and know that you will not overpower Allah, and Allah will disgrace the disbelievers.
The Repentance/9:3
This is also a proclamation from Allah and His Messenger to all the people on the day of the great pilgrimage: Allah is far from the idolaters, and so is His messenger. It is better for you if you repent. And if you turn back, know that you cannot overpower Allah. Announce to the disbelievers a painful punishment.
The Repentance/9:4
But keep the agreement of the pagans who have kept the terms of your agreement with them, and have not collaborated with others against you, for as long as you recognize it. God loves the righteous.
The Repentance/9:5
When the holy months are over, kill the pagans wherever you find them (if they still refuse to make peace). Seize them, encircle them and watch their every move. If they repent and pray and pay zakat, then let them go free. Allah is Forgiving, Merciful.
