سورة An-Najm ( The Star ) - الآية 32

Those who avoid great sins and Al-Fawahish (immoral sins) except Al-Lamam -- verily, your Lord is of vast forgiveness. He knows you well when He created you from the earth (Adam), and when you were fetuses in your mothers' wombs. So, ascribe not purity to yourselves. He knows best him who has Taqwa.
