الآية رقم (81) - وَيَقُولُونَ طَاعَةٌ فَإِذَا بَرَزُواْ مِنْ عِندِكَ بَيَّتَ طَآئِفَةٌ مِّنْهُمْ غَيْرَ الَّذِي تَقُولُ وَاللّهُ يَكْتُبُ مَا يُبَيِّتُونَ فَأَعْرِضْ عَنْهُمْ وَتَوَكَّلْ عَلَى اللّهِ وَكَفَى بِاللّهِ وَكِيلاً

(81) - {And they say, “obedience." But when they leave you, a group of them spend the night determining to do other than what you say. But Allah records what they plan by night. So leave them alone and rely upon Allah. And sufficient is Allah as Disposer of affairs.}

The talk is about the hypocrites.

( فَأَعْرِضْ عَنْهُمْ وَتَوَكَّلْ عَلَى اللَّهِ ) (…So leave them alone and rely upon Allah.…): Allah (swt) does not order to kill or fight them but to leave them and rely on Allah (swt) because as afore-mentioned, those, to whom the Prophet (saws) have been sent will not aid him, rather he will be aided by The One Who sent him, so he has to rely upon Him. This is a clear evidence from the Holy Qur’an about the freedom of choice.  

( وَكَفَىٰ بِاللَّهِ وَكِيلً ) (…And sufficient is Allah as Disposer of affairs.): A person uses a procurator to relief himself – for example, he appoints a lawyer to defend him, and when Allah (swt) is entrusted as Disposer of affairs then the result is:

 وَمَن يَتَوَكَّلۡ عَلَى ٱللَّهِ فَهُوَ حَسۡبُهُۥٓۚ إِنَّ ٱللَّهَ بَٰلِغُ أَمۡرِهِ

(And will provide for him from where he does not expect. And whoever relies upon Allāh – then He is sufficient for him. Indeed, Allāh will accomplish His purpose) (At-Talaq: 3)

Indeed Allah (swt) is perfect and He is The He has the power that cannot be defeated and He can carry out His Will, Who says to a thing: “Be,” and it is, and no one can reverse His judgment.
