The following verses not only drills home the importance of revelations as a whole but gives us a heads up on why Quran is the only 100% reliable version of these revelations. That doesn’t mean the other scriptures are worthless now but Quran is the go to version when in doubt:

2:37 Then received Adam from his Lord words, So (his Lord) turned towards him. Indeed He! He (is) the Oft-returning (to mercy), the Most Merciful.

46:12 And from before it (was the) Scripture (of) Musa (as) a guide and a mercy. And this (is) a Book confirming it, (in) language Arabic to warn those who do wrong and glad tidings for the good-doers.

5:13 So for their breaking of the covenant, We cursed them and made their hearts hard. They distort (يحرفون) words from their proper places usages and have forgotten a portion of that of which they were reminded. And you will still observe deceit among them, except a few of them. But pardon them and overlook [their misdeeds]. Indeed, God loves the doers of good.

5:15 O People (of) the Book! Surely has come to you Our Messenger making clear to you much of what you used to conceal of the Scripture and overlooking of much. Surely has come to you from God a light and a Book clear

7:52 “For We had certainly sent to them a Book based on knowledge, which We explained in detail (Arabic: fasalnahu), a guide and a mercy to all who believe”Once again, the following verse is significant because as Muslims we are not to abandon the Quran, nothing else is referenced here. Just the Quran.

25:30 “And the Messenger will say: O my Lord! my people deserted this Quran.”

6:19 ” …”What thing is greatest in testimony?” Say, ” God is witness between me and you. And this Qur’an was revealed to me that I may warn you thereby …” Guidance is with God and nobody else, yes we may listen to those who may have a take on what God is telling us in the Quran and then decide if their opinion makes sense but that is the extent of it.

10:35 Say, “Of your ‘partners’ is there any that can lead you to the Truth?” Say, “God leads to the Truth. So, who is more worthy of being followed? The One Who shows you the Way or he who finds no way unless he is guided? What is amiss with you? How do you judge?”

7:30 A group He guided and a group deserved – [on] they the straying. Indeed, they take the devils (as) allies from besides God while they think that they (are the) guided-ones. How to deal with those who are astray but stand convinced that they are on the right path? Once we have discounted the possibility that their aim is to deliberately deceive, we must cross check everything with the book of God and try to gently point out the discrepancies in their understanding.

25:63 And (the) slaves (of) the Most Gracious (are) those who walk on the earth (in) humbleness and when address them the ignorant ones, they say, “Peace.”While dealing with people we have to keep one very important thing in mind and give them slack if they are still below the age of maturity.

46:15 And We have enjoined (on) man to his parents kindness. Carried him his mother (with) hardship and gave birth to him (with) hardship. And (the) bearing of him and (the) weaning of him (is) thirty month(s) until, when he reaches his maturity and reaches forty year(s), he says, “My Lord, grant me (the) power that I may be grateful (for) Your favor which You have bestowed upon me and upon my parents and that I do righteous (deeds) which please You, and make righteous for me among my offspring, indeed, I turn to You and indeed, I am of those who submit.”A lifestyle of moderation and humbleness should be a guiding principle in almost everything we do

25:67 And those who, when they spend, (are) not extravagant and not are stingy but are between that – moderate.

2:45 And seek help through patience and the prayer; and indeed, it (is) surely difficult except on the humble ones

7:55 Call upon your Lord humbly and secretly. Indeed, He (does) not love the transgressors.We must be aware of our deeds and keep the following ratios in mind. It is important because stressing over how we are doing is not the main purpose of our existence. Unless one is hell bent on evil, these odds are next to impossible to beat.

6:160 Whoever came with a good deed, then for him (is) ten (times) the like of it. And whoever came with an evil deed then not he will be recompensed except the like of it, and they not will be wronged.

27:11 Except who wrongs then substitutes good after evil, then indeed, I Am Oft-Forgiving, Most Merciful.While the above verses should put our minds at ease, the following verse reminds us that God will still test us a couple of times a year.

29:02 Do think the people that they will be left because they say, “We believe” and they not will be tested?

3:186 You will certainly be tested in your wealth and yourselves. And you will certainly hear from those who were given the Book from before you and from those who associate partners with God – hurtful things many, and if you are patient and fear (God) then indeed, that (is) of the matters (of) determination.Walk the talk and not do as I say but do as I do is the rule.

61:2 O you who believe! Why (do) you say what not you do?

61:3 Great is hatred with God that you say what not you do?We have to prepared for our eventual goodbye from this world and be aware of what to expect.

8:50 And if you (could) see when take away souls (of) those who disbelieve the Angels, striking their faces and their backs “Taste (the) punishment (of) the Blazing Fire.”Never forget it is all about the return.

2:46 Those who believe that they will meet their Lord and that they to Him will returnPut this life in clear perspective, it is just a day or even less than that, just imagine!

23:112 He will say, “How long did you remain in the earth, (in) number (of) years?”

23:113 They will say, “We remained a day or a part (of) a day; but ask those who keep count.”

23:114 He will say, “Not you stayed but a little, if only you [you] knew.

23:115 Then did you think that We created you uselessly and that you to Us not will be returned?”

36:52 They [will] say, “O woe to us! Who has raised us from our sleeping place?” “This (is) what (had) promised the Most Gracious, and told (the) truth the Messengers.”

The bar for mere salvation could not be any lower.5:69 Indeed, those who believed and those who became Jews and the Sabians and the Christians, whoever believed in God and the Day the Last. and did good deeds, then no fear on them and not they will grieve.
