“It is not helping our cause.”
‘’Fight and kill the disbelievers wherever you find them, and seize them,
beleaguer them and lie in wait for them in every stratagem of war...” (Quran
9:5) || “O you who believe! Do not take the Jews and the Christians for
friends; for they are friends but of each other; and whoever amongst you
takes them for a friend, then surely he is one of them; surely Allah does
not guide the unjust people.” (Quran 5:51)
And whose cause is that? n/s
When you march up to attack a city, make its people an offer of peace.
If they accept and open their gates, all the people in it shall be subject to forced labor and shall work for you.
If they refuse to make peace and they engage you in battle, lay siege to that city.
When the LORD your God delivers it into your hand, put to the sword all the men in it.
As for the women, the children, the livestock and everything else in the city, you may take these as plunder for yourselves. And you may use the plunder the LORD your God gives you from your enemies.
This is how you are to treat all the cities that are at a distance from you and do not belong to the nations nearby.
However, in the cities of the nations the LORD your God is giving you as an inheritance, do not leave alive anything that breathes.
Completely destroy themthe Hittites, Amorites, Canaanites, Perizzites, Hivites and Jebusitesas the LORD your God has commanded you.
Deuteronomy 20:10-17
