More than 1,000 Yazidi women had already been captured by Isis as Kurdish soldiers advanced on Mosul and hundreds more are believed to have been abducted as part of the group’s mission to eradicate other religions in its Sunni-dominated Islamic “caliphate”.
And know that whatever of war-booty that you may gain, verily one-fifth (1/5th) of it is assigned to Allâh, and to the Messenger, and to the near relatives [of the Messenger (Muhammad SAW)], (and also) the orphans, Al-Masâkin (the poor) and the wayfarer, if you have believed in Allâh and in that which We sent down to Our slave (Muhammad SAW) on the Day of criterion (between right and wrong), the Day when the two forces met (the battle of Badr) – And Allâh is Able to do all things.
And He caused you to inherit their lands, and their houses, and their riches, and a land which you had not trodden (before). And Allâh is Able to do all things. http://www.islam-watch.org/logical/Allah-make-War-Booty-Halal-Prophet-Muhammad.htm
Ibn Ishaq (327) – “Allah made booty lawful and good. He used it to incite the Muslims to unity of purpose. So enjoy what you have captured.”
Ibn Ishaq (503) – “Allah saw what was in their hearts [what they coveted] so he rewarded them with victory and with as much spoil as they could take. Allah promised that they would soon capture a great deal of booty.” 508 goes on to say that, “Whenever they heard of a Meccan caravan setting out for Syria, they intercepted it, and killed everyone they could get a hold of. They tore every caravan to pieces and took the goods.”) http://www.thereligionofpeace.com/Quran/020-stealing.htm
Al-Anfal is the eighth sura or chapter of the Qur’an which explains the triumph of 313 followers of the new Muslim faith over almost 900 pagans at the Battle of Badr in 624 AD. Al Anfal literally means the spoils (of war) and was used to describe the military campaign of extermination and looting commanded by Ali Hassan al-Majid. His orders informed jash (literally “donkey’s foal” in Kurdish) units that taking cattle, sheep, goats, money, weapons and even Kurdish women was legal. http://en.wikipedia.org/wiki/Al-Anfal_Campaign
