Jihad in the Koran
In making war on the unbelievers, Allah reminded the believers not to let the booty distract them from their immediate goal which is shedding the blood of those who refuse to submit to His Will.
8:67 It is not up to any Prophet to take captives except after too much blood is shed (after the enemy is hard hit and subdued) in the land. You desire the fleeting goods of this world, but Allah desires the Hereafter, and Allah is Mighty, Wise.
Revealed truths which confirm the inalienable right of a believer to the property (both eatable and uneatable) and the wife and kids of an unbeliever he has slaughtered.
8:68 But for a prior ordinance of Allah, you would have been afflicted on account of what you have taken (an ordinance which made it lawful for Muslims to take spoils and captives) by a terrible punishment.
8:69 So eat of the lawful and good things you have taken as booty. Fear Allah; Allah is truly All-Forgiving, Merciful.
The right of the believer to the property of a slain unbeliever is also confirmed in a saying of the Prophet where he makes terror a valid tactic in getting all to submit to the Will of Allah.
Narrated Abu Huraira:
Allah's Apostle said, "I have been sent with the shortest expressions bearing the widest meanings, and I have been made victorious with terror (cast in the hearts of the enemy), and while I was sleeping, the keys of the treasures of the world were brought to me and put in my hand."
If sharing in the booty is not sufficient to convince you to submit to Allah’s Will, remember that in Allah’s eyes you are traitors, with all the horrifying stuff that implies, with your continued enslavement the best that you can hope for.
8:70 O Prophet, tell those captives in your keeping: “If Allah knows of any good in your hearts, He will give you in return better than what has been taken from you and forgive you.” Allah is All-Forgiving, Merciful.
8:71 But if they wish to betray you, they have previously betrayed Allah, and so He subdued them. Allah is All-Knowing, Wise.
A revealed truth within a hadith (both reinforcing each other) meant to reduce the resistance of the believers to raping their female captives in front of their husbands.
The Apostle of Allah (may peace be upon him) sent a military expedition to Awtas on the occasion of the battle of Hunain. They met their enemy and fought with them. They defeated them and took them captives.
Some of the Companions of the Apostle of Allah (may peace be upon him) were reluctant to have intercourse with the female captives in the presence of their husbands who were unbelievers. So Allah, the Exalted, sent down the Qur’anic verse: (4:24) "And all married women (are forbidden) unto you save those (captives) whom your right hands possess."
Abu Dawud 2.2150
Until God’s Messenger made his views known, some holy warriors were also unsure about whether coitus interruptus was halal. They consulted with the Prophet who made his and what has to assume God's views on a believer withdrawing his member from his captive's vagina prior to ejaculation.
Narrated Abu Said Al-Khudri: that while he was sitting with Allah's Apostle he said, "O Allah's Apostle! We get female captives as our share of booty, and we are interested in their prices, what is your opinion about coitus interruptus?"
The Prophet said, "Do you really do that? It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence."
Abu Sirma said to Abu Sa'id al Khadri (Allah be pleased with him): 0 Abu Sa'id, did you hear Allah's Messenger (may peace be upon him) mentioning al-'azl?
He said: Yes, and added: We went out with Allah's Messenger (may peace be upon him) on the expedition to the Bi'l- Mustaliq and took captive some excellent Arab women; and we desired them, for we were suffering from the absence of our wives, (but at the same time) we also desired ransom for them. So we decided to have sexual intercourse with them but by observing 'azl (Withdrawing the male sexual organ before emission of semen to avoid conception).
But we said: We are doing an act whereas Allah's Messenger is amongst us; why not ask him?
So we asked Allah's Messenger (may peace be upon him), and he said: It does not matter if you do not do it, for every soul that is to be born up to the Day of Resurrection will be born.
Imam Muslim 8:3371
As reported by the BBC, the Prophet's views on coitus interruptus and by extension contraception have encouraged "more conservative Islamic leaders have [to] openly campaign against the use of condoms or other birth control methods, thus making population planning in many countries ineffective."
While a majority of Islamic Schools of Law allow contraceptives within a marriage setting, all are against men having a vasectomy or women a tubal ligation for this would be interfering with Allah's right to schedule a pregnancy at some point in the future.
Greetings and the Booty
4:86 And when you are greeted with a certain greeting, greet back with a better one or return it; for Allah keeps count of everything.
4:94 O believers, if you journey in the Way of Allah, be discerning and do not say to him who greets you: “You are not a believer”, seeking the fleeting goods of the present life. For with Allah are abundant gains. This is how you were before and Allah has been gracious to you; so discern well. Allah is indeed fully aware of what you do!
In the early days of Islam the greeting as-salam 'alaykum ('peace be on you') was a distinguishing symbol of the Muslims. When a Muslim greeted another Muslim with this expression it signified that he was a member of the same community… from whom he need entertain no fear of hostility and towards whom, in return, he should not behave with hostility.
[This caused a problem] on the battlefield. Whenever a Muslim was in danger of being harmed inadvertently by other Muslims during the fighting, he resorted to either the Islamic greeting (as-salam 'alaykum) or the Islamic creed There is no god save Allah' (ili-Jl) in order to indicate that he was their brother-in-faith.
The Muslims, however, often suspected this to be merely a ruse of the enemy and therefore sometimes disregarded the utterance of the Islamic greeting or of the Islamic creed, and killed such people and seized their belongings as booty.
… God solved the problem by revelation. The purport of the verse is that no one has the right summarily to judge those who profess to be Muslims, and assume them to be lying for fear of their lives … The error of letting an unbeliever go unpunished is preferable to that of killing a true believer.
Learn how to say the life-saving words correctly:
Narrated Ibn 'Umar:
The Prophet sent (an army unit under the command of) Khalid bin Al-Walid to fight against the tribe of Bani Jadhima and those people could not express themselves by saying, "Aslamna (we profess Islam)," but they said, "Saba'na! Saba'na!"
Khalid kept on killing some of them and taking some others as captives, and he gave a captive to everyone of us and ordered everyone of us to kill his captive ...
