quran

وَمِنْ ءَايَـتِهِ خَلْقُ السَّمَـوَتِ وَالاٌّرْضِ وَاخْتِلَـفُ أَلْسِنَتِكُمْ وَأَلْوَنِكُمْ إِنَّ فِى ذلِكَ لأَيَـتٍ لِّلْعَـلَمِينَ

And among His signs is the creation of the heavens and the earth, and the difference of your languages and colors. Verily, in that are indeed signs for men of sound knowledge

Ruum : 22
