Re: Arguments against Quran Only/Hadith rejectors
Sure thing:
4:64 We have sent no Messenger but that he should be obeyed by Allah’s leave. (Why then is the Torah and Gospel mentioned and not the Hadith/Sunnah of Moses and Jesus?) They are not sent with hypotheses, but to show people how they can establish an equitable society, in which people flourish individually and collectively. They attain personal development and become worthy of immortal life in the Paradise (89:29). If anyone hurts his or her "Self" by transgressing His Laws, or wrongs a member of the community, he or she must come to the Messenger, the Central Authority of the System, to make amends. Sitting back at home and praying in hiding won’t help (9:102-105, 20:82, 5:10). The Messenger will then, decide the matter seeing if there is room for forgiveness in the Divine Law. Such is the Moral Order that the Messenger has inculcated in the hearts and in the society where one becomes the watcher over one's own "Self" (8:74-75, 9:100, 48:29, 59:8-9). Indeed, there is plenty of room for making amends, and for mercy in the Divine System. Allah is Acceptor of repentance, Merciful.
4:65 By your Lord, They do not really believe unless they make you (O Prophet) a judge in all their disagreements. And then find no hesitation in their hearts in accepting your judgment, and submit with full submission.
4:66 And if We had decreed for them, “Lay down your lives,” or “Forsake your homelands,” a few of them would do it. Although, if they did as was admonished, it would be for their own good, and a cause for strengthening themselves.
4:80 Whoever obeys the Messenger, automatically obeys Allah since he rules by the Book of Allah (5:44). But if they turn away, We have not sent you as a watcher over them.
4:81 They express verbal allegiance to the System, “It is Obedience!” But when they go away from you a party of them spends the night in planning against the Belief System you preach. They discuss ways to corrupt the Message. Allah records what they plan by night. Ignore them, go ahead with your Program and trust in Allah (6:107). Allah is Sufficient as Guardian.
4:82 Will they not then, try to understand this Qur’an? (This does not say through what the prophet explains to you on his own) If it were from other than Allah (one more indication - the prophet could not have added to Allah's message) they would surely have found in it much contradiction.
8:20 O You who have chosen to be graced with belief! Obey Allah and His Messenger. Listen to him when he speaks, without getting distracted. (The only thing we know and can be DEAD sure of what those around the prophet heard him say, was the Quran - the hadith are narrations from what people had remembered ... and most of it was collected at least a couple of centuries later - look at the timeline of hadith collection)
AND THEN :)
4:87 Allah! There is no god but He. He will summon all of you on the Day of Resurrection about the advent of which there is no doubt. Who can tell you a more reliable HADITH (saying) than Allah?
7:185 Can they not see (and correlate what he tells them with) the Dominion of the heavens and the earth and what Allah has created? Does it ever occur to them that the end of their own life may be near (hence the time to make the right decisions is not unlimited)? What HADITH besides the Qur’an, are they going to believe after him?
