الآية رقم (4) - وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ

(4) - (Nor is there to Him any equivalent." (4))

كُفُوًا (equivalent): Equal, compatible or similar, Allah (swt) is unique in His oneness, attributes and His deeds. He has no counterpart, there is none higher than Him:

  لَيْسَ كَمِثْلِهِ شَيْءٌ ۖ وَهُوَ السَّمِيعُ الْبَصِيرُ﴿

 (There is nothing like unto Him, and He is the Hearing, the Seeing.) (Ash-Shura: 11)

Allah (swt) is unique in His ability, strength, creating, and all His attributes, no compatible or counterpart whatsoever to Him.
