Tafsir of Al-An'am 6:18

At the end of verse 18, it was said: وَهُوَ الْقَاهِرُ‌ فَوْقَ عِبَادِهِ ۚ وَهُوَ الْحَكِيمُ الْخَبِيرُ‌ ﴿١٨﴾ (And He is dominant over His slaves, and He is the Ali-Wise, the All-Aware). It means that the mastery of Allah Ta` ala prevails over His servants in the absolute sense and that everyone remains under His power and control all the time. This is the reason why no human be¬ing, no matter how great, whether a prophet close to Allah, or the most powerful ruler of the world, nine of them come out successful in everything they do, nor is every wish of theirs granted.

And then, He is Wise too, for everything He does is essential Wis¬dom. And then, He is All-Aware too, for He is the One who knows everything. Thus, by the word, al-Qahir (the Dominant) pointed to is the perfect power of Allah Ta` ala and, by the word, al-Hakim (the All-Wise), His all-encompassing knowledge - and the two tell us that per¬fection in knowledge and power are the sole attributes of Almighty Al¬lah and it is only Him that they belong to.
