Ar-Rum 30:22
وَمِنْ ءَايَـٰتِهِۦ خَلْقُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ وَٱخْتِلَـٰفُ أَلْسِنَتِكُمْ وَأَلْوَٰنِكُمْ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّلْعَـٰلِمِينَ
Wamin ayatihi khalqu assamawatiwal-ardi wakhtilafu alsinatikumwaalwanikum inna fee thalika laayatinlilAAalimeen
"And of His signs is the creation of the heavens and the earth and the diversity of your languages and your colors. Indeed in that are signs for those of knowledge."
Ar-Rum 30:22, translation by Sahih International
A short reflection
Among His signs is the creation of the heavens and the earth, and the difference of your tongues and colours. In that are signs for the learned.
