Tafsir of Al-Insan 76:30

وما تشاوون إﻻ أن يشاء الله

But you cannot will, unless Allah wills. meaning, no one is able to guide himself, enter into faith or bring about any benefit for himself,

إﻻ أن يشاء الله إن الله كان عليما حكيما

Unless Allah wills. Verily, Allah is Ever All-Knowing, All-Wise. meaning, He is Most Knowledgeable of who deserves to be guided. So, He makes guidance easy for him and He predestines for him that which will be a cause for it. However, whoever deserves misguidance, He averts guidance from him. Unto Him belongs the most excellent wisdom and the most irrefutable argument. Thus, He says,

إن الله كان عليما حكيما

Verily, Allah is Ever All-Knowing, All-Wise. Then He says,

يدخل من يشاء في رحمته

والظالمين أعد لهم عذابا أليما
