Walaikum assalam warahmatullahi wabarakatuhu. There are indeed many such passages in the Quran that talk about the charecteristics of the Quran. I have specifically picked out two of these passages. The Quran talks more about paradise, and hence it is too volumnous for someone like me to even try and collect them all together. As for tafseer of these ayaahs, it is always available alhamdulillah, even in English these days you can find the tafseer of ibn kathir at http://www.qtafsir.com

23:57 Indeed,they who r apprehensive from fear of their Lord
23:58 And they who believe in the signs of their Lord
23:59 And they who do not associate anything with their Lord
23:60 And they who give what they give while their hearts are fearful because they will be returning to their Lord
23:61 It is those who hasten to good deeds, and they outstrip [others] therein.

Also Surah Ma’rij has few,
70:23 Those who are constant (da’imoon) in their prayer
70:24 And those within whose wealth is a known right – For the petitioner and the deprived
70:25 And those who believe in the Day of Recompense
70:27 And those who are fearful of the punishment of their Lord – Indeed, the punishment of their Lord is not that from which one is safe
70:29 And those who guard their private parts, Except from their wives or those their right hands possess, for indeed, they are not to be blamed, But whoever seeks beyond that, then they are the transgressors
70:32 And those who are to their trusts and promises attentive
70:33 And those who are in their testimonies upright
70:34 And those who [carefully] maintain their prayer:
70:35 They will be in gardens, honored.
