How can any spiritual scripture be used as justification for mass murder? How can the tenet that The Prophet ought never be depicted ever override Islam’s most mundane greeting AsSalaam alaikum – “peace and mercy be upon you”? It can’t and it doesn’t.
The young, bewildered, pitiable men that carry out these atrocities probably at the behest of older, power hungry men do not speak for Islam or Muhammad or Allah.
This language has nothing to do with the God I believe in or the God any of the Muslims I know believe in.
The following are versus from The Qur'an, Surah (Chapter) 9:
And when the sacred months have passed, then kill the polytheists [Mohammed considered Christians polytheists because of the Christian doctrine of the Trinity: Father, Son, and Holy Spirit as The One God] wherever you find them and capture them and besiege them and sit in wait for them at every place of ambush. But if they should repent, establish prayer, and give zakah, let them [go] on their way. Indeed, Allah is Forgiving and Merciful. (9:5; Surah 9:Verse 5)
O you who have believed, indeed the polytheists ["pagans" but the term also refers to Christians, ...] are unclean, so let them not approach al-Masjid al-Haram after this, their [final] year. And if you fear privation, Allah will enrich you from His bounty if He wills. Indeed, Allah is Knowing and Wise. (9:28)
Fight those who do not believe in Allah [Jews, Christians, ...] or in the Last Day and who do not consider unlawful what Allah and His Messenger have made unlawful and who do not adopt the religion of truth from those who were given the Scripture - [fight] until they give the jizyah [taxes, tribute, protection money; it's where some of the "bounty" comes from] willingly while they are humbled. (9:29)
The Jews say, "Ezra is the son of Allah "; and the Christians say, "The Messiah [Jesus] is the son of Allah." That is their statement from their mouths; they imitate the saying of those who disbelieved [before them]. May Allah destroy them; how are they deluded? (9:30)
If you do not go forth [do not fight and kill], He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent. (9:39)
What the above means is that the Christians and others will either convert or submit and pay protection money (extortion) or be killed. That's not even the half of it. The women will be forced to have sex (forcibly raped) and many, if not all, will be sold into sexual slavery.
So, Russell Brand is, frankly, very ignorant on the subject of Islam, Islamic terrorism, and the Islamic State (which is actually carrying out the commandments of The Qur'an, Surah 9), etc.
Russell Brand has bought into a sugarcoated interpretation of the Qur'an where the terrible deeds done on the orders of Mohammed, things which were and are completely disallowed by the commandments of Jesus, were done only at the end of the particular battle and which, according to the sugarcoated view, we are to take it, would possibly/maybe/it's unclear (most of the "moderates" appear to be unsure) never be repeated and that the verses cannot be used by the terrorists to justify what those terrorists are doing in their war against those fighting against those very verses, the spirit of those verses.
To give you an example in "Christianity" as some hold it, we have many who profess Romans 13:
Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God. Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation. For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? do that which is good, and thou shalt have praise of the same: For he is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil. (Romans 13:1-4 KJV)
Many people professing Christianity take that and follow the orders of the "powers that be," such as George W. Bush was when George took the US into a criminal war against Iraq.
Wherefore ye must needs be subject, not only for wrath, but also for conscience sake. (Romans 13:5 KJV)
So, George being wrathful and taking it out on the Iraqis, is something Paul wrote I must be subject to without objection because to object is to go against God.
Then he goes on to say:
For for this cause pay ye tribute also: for they are God's ministers, attending continually upon this very thing. Render therefore to all their dues: tribute to whom tribute is due; custom to whom custom; fear to whom fear; honour to whom honour. Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law. And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed. The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light. Let us walk honestly, as in the day; not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying. But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof. (Romans 13:6-14 KJV)
When taken all together and in contrast to the actual teaching of Jesus concerning "wrath" and whether Christians ought to act out on it right along with the "powers that be" (which Jesus said we should not), we have Paul sending out an extremely confused message, an anti-Christ message, whether wittingly or not.
And it came to pass, when the time was come that he should be received up, he stedfastly set his face to go to Jerusalem, And sent messengers before his face: and they went, and entered into a village of the Samaritans, to make ready for him. And they did not receive him, because his face was as though he would go to Jerusalem. And when his disciples James and John saw this, they said, Lord, wilt thou that we command fire to come down from heaven, and consume them, even as Elias did? But he turned, and rebuked them, and said, Ye know not what manner of spirit ye are of. For the Son of man is not come to destroy men's lives, but to save them. And they went to another village. (Luke 9:51-56 KJV)
The difference concerning Islam is that the verses in chapter 9 of the Qur'an are directly from Mohammed and are every bit as inconsistent with "love" at least as defined by Jesus in the Gospels, which the Muslims reject, by definition.
