Qur'an 48:29—Muhammad is the Messenger of Allah, and those who are with him are severe against disbelievers, and merciful among themselves. You see them bowing and falling down prostrate (in prayer), seeking Bounty from Allah and (His) Good Pleasure. The mark of them (i.e. of their Faith) is on their faces (foreheads) from the traces of (their) prostration (during prayers). This is their description in the Taurat (Torah). But their description in the Injeel (Gospel) is like a (sown) seed which sends forth its shoot, then makes it strong, it then becomes thick, and it stands straight on its stem, delighting the sowers that He may enrage the disbelievers with them. Allah has promised those among them who believe (i.e. all those who follow Islamic Monotheism, the religion of Prophet Muhammad SAW till the Day of Resurrection) and do righteous good deeds, forgiveness and a mighty reward (i.e. Paradise).
Qur'an 4:24—Also (forbidden are) women already married, except those (captives and slaves) whom your right hands possess. Thus hath Allah ordained (Prohibitions) against you: Except for these, all others are lawful, provided ye seek (them in marriage) with gifts from your property—desiring chastity, not lust, seeing that ye derive benefit from them, give them their dowers (at least) as prescribed; but if, after a dower is prescribed, agree mutually (to vary it), there is no blame on you, and Allah is All-knowing, All-wise.
Qur'an 5:33—The punishment of those who wage war against Allah and His apostle and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides or they should be imprisoned; this shall be as a disgrace for them in this world, and in the hereafter they shall have a grievous chastisement.
Qur'an 9:5—Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful.
Qur'an 9:29—Fight those who believe not in Allah nor the Last Day [notice it says "fight those who do not believe," not "fight people who are attacking you"], nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the Religion of Truth, from among the People of the Book [the people of the book are Jews and Christians], until they pay the Jizyah with willing submission, and feel themselves subdued.
Qur'an 9:73—O Prophet! strive hard against the unbelievers and the hypocrites and be unyielding to them; and their abode is hell, and evil is the destination.
Qur'an 9:111—Surely Allah has bought of the believers their persons and their property for this, that they shall have the garden; they fight in Allah's way, so they slay and are slain; a promise which is binding on Him in the Taurat and the Injeel and the Quran; and who is more faithful to his covenant than Allah? Rejoice therefore in the pledge which you have made; and that is the mighty achievement.
Qur'an 47:35—Be not weary and fainthearted, crying for peace, when ye should be uppermost: for Allah is with you, and will never put you in loss for your (good) deeds.
Qur'an 2:106—Whatever communications We abrogate or cause to be forgotten, We bring one better than it or like it. Do you not know that Allah has power over all things?
