Tafsir of Muhammad 47:26

ذلك بٲنهم قالوا للذين كرهوا ما نزل الله سنطيعكم في بعض اﻻمر

That is because they said to those who hate what Allah sent down: "We will obey your in part of the matter.' means, they plotted secretly with them and gave them evil advice -- as is the common practice of the hypocrites who declare the opposite of what they conceal. Because of this, Allah says,

والله يعلم إسرارهم

And Allah knows their secrets. whatever they hide and conceal, Allah is well-acquainted with it and He knows it. This is similar to His saying,

والله يكتب ما يبيتون

And Allah records all that they plot by night. (4:81) Allah then says,

فكيف إذا توفتهم المﻼيكة يضربون وجوههم وأدبارهم
