The Creator of the heavens and the earth. He has made for you mates from yourselves, and for the cattle (also) mates. By this means He creates you.
There is nothing like Him and He is the All-Hearer, the All-Seer.
لَيْسَ كَمِثْلِهِ شَىْءٌ
There is nothing like Him means, there is nothing like the Creator of these pairs, for He is the Unique, the Self-Sufficient Master, Who has no peer or equal.
