The Thunder - 13:37 So We sent it down as an Arabic law. If you follow their pleasure after the knowledge that has come to you, you will have no friend or protector against Allah.
What is the intention?
The Kneeling/45:18 Then We gave you a law about religion; you should follow it, and do not follow the whims of those who do not know.
The Kneeling/45:19 They cannot ward off from you anything from Allah. The wrongdoers are each other´s friends. And Allah is the friend of the righteous.

The Night Journey/17:73 They would almost have led you astray from what We have revealed to you so that you might invent something else and attribute it to Us. Then they would have taken you as a friend.
The Night Journey/17:74 If We had not made you firm, you would almost have inclined to them a little
The Night Journey/17:75 Then We would have made you taste the torment of life and death multiplied, then you would not have found any helper against Us.

The Sure Truth/69:44 If He attributes to us some words,
The Sure Truth/69:46 Then We would cut off the revelation from him.
The Sure Truth/69:47 And no one of you could prevent it.

The Cow/2:120 "Neither the Jews nor the Christians will be pleased with you unless you enter into their religion. Say: "The right way is the way of Allah."If you follow their desires after the knowledge that has come to you, you will find neither a friend nor a supporter to defend you against Allah."

The Heights/7:6 We will question those to whom a message was sent, and We will question the messengers.
