The Qu'ran says...

(In some sort of odd old-englishy translation)

"And walk not on the earth with conceit and arrogance. Verily, you can neither rend nor penetrate the earth, nor can you attain the stature like the mountains in height."

"This is (part) of the al-hikmah ( wisdom, good manners, and high character, etc.) which your Lord inspired to you. And set not up with Allah any other god lest you should be thrown into Hell, blameworthy and rejected ( from His Mercy.)"

[Translation from the Quran 17:33-39]

"Those who believed and led a righteous life are the best creatures."
[98:7]

"O mankind! We created you from a single soul, male and female, and made you into nations and tribes, so that you may come to know one another. Truly, the most honored of you in Gods sight is the greatest of you in piety. God is All-Knowing, All-Aware."
[49:13]

"And the servants of Allah . . . are those who walked on the earth in humility, and when the ignorant address them, they say 'Peace'"
[25:63]

"The recompense for an injury is an injury equal thereto: but if a person forgets and makes reconciliation, his reward is due from Allah."
[62:40]

"They are the ones who examine all words, then follow the best. These are the ones whom GOD has guided; these are the ones who possess intelligence."
[39:18]

"Not so the worshippers who are steadfast in prayer; who set aside a due portion of their goods for the needy and the dispossessed; who truely believe in the Day of Reckoning and dread the punishment of their Lord (for none is secure from the punishment of their Lord); who restrain their carnal desire (save with their wives and slave-girls, for these are lawful to them; he that lusts after other than these is a transgressor); who keep their trusts and promises and bear true witness; who attend to their prayers with promprirude. These shall be laden with honours and shall dwell in fair gardens."
