Amongst the benefits of this Ayah; is a warning from oppression due to His statement:
And Allah does not guide oppressors.
It is a form of oppression, that the truth becomes apparent to you, but you continue to argue in support of your own opinion, we ask Allah for safety from this; the truth becomes apparent to you, but you argue in support of your opinion. This is indeed oppression, because justice is to submit to and follow the truth, and to refrain from being arrogant when it becomes clear. For this reason, we ask Allah for safety, for you as well as us.
Amongst the benefits: Is that Allah - the Mighty and Magnificent - does not prevent anyone from His graciousness, except if the prohibited thing itself that was mentioned, was the cause [of prevention from His graciousness], due to His statement:
And Allah does not guide oppressors
Aal ‘Imran: 86
So because of their oppression, Allah does not guide the, and it is similar to His Statement:
So when they deviated, Allah caused their hearts to deviate.As-Saff: 5
