Quran 35.31-32
As for that which We inspire in thee of the Scripture, it is the Truth confirming that which was (revealed) before it. Lo! Allah is indeed Observer, Seer of His slaves. Then We gave the Scripture as inheritance unto those whom We elected of Our bondmen. But of them are some who wrong themselves and of them are some who are lukewarm, and of them are some who outstrip (others) through good deeds, by Allah's leave. That is the great favour!
