There is nothing similar to God

لَيْسَ كَمِثْلِهِ شَيْءٌ

فَاطِرُ السَّمَاوَاتِ وَالْأَرْضِ جَعَلَ لَكُم مِّنْ أَنفُسِكُمْ أَزْوَاجًا وَمِنَ الْأَنْعَامِ أَزْوَاجًا يَذْرَؤُكُمْ فِيهِ لَيْسَ كَمِثْلِهِ شَيْءٌ وَهُوَ السَّمِيعُ الْبَصِيرُ

He is the Creator of the heavens and the earth. He has made for you pairs from among yourselves, and pairs from the cattle. He makes you expand in this way. Nothing is like Him. And He is the All-Hearing, the All-Seeing.

— Quran 42:11

in order to worship God, we have to know Him well otherwise we may form a distorted concept of Him and then go astray. God is nothing like a human being or like anything that we can imagine and he is the only one worthy of worship.

لَيْسَ كَمِثْلِهِ شَيْءٌ

There is nothing similar to God.

— Quran 42:11

The Quran answers such questions as where we came from, why we exist and what we should do. This Book describes the existence, the unity, the power and the mercy of God. The Quran speaks of God, and introduces God as the Merciful, the Creator and the Forgiver. The description of God is the most important message of the Quran.
