And say: Truth hath come and falsehood hath vanished away. Lo! falsehood is ever bound to vanish. Quran 17:81

Mankind were one community, and Allah sent (unto them) prophets as bearers of good tidings and as warners, and revealed therewith the Scripture with the truth that it might judge between mankind concerning that wherein they differed. And only those unto whom (the Scripture) was given differed concerning it, after clear proofs had come unto them, through hatred one of another. And Allah by His Will guided those who believe unto the truth of that concerning which they differed. Allah guideth whom He will unto a straight path. 2:213

(Alms are) for the poor who are straitened for the cause of Allah, who cannot travel in the land (for trade). The unthinking man accounteth them wealthy because of their restraint. Thou shalt know them by their mark: They do not beg of men with importunity. And whatsoever good thing ye spend, lo! Allah knoweth it. Quran 2:273
