52:26At-Tur

When the Prophet (ﷺ) feared a (group of) people, he would say: "O Allah, we make Thee our shield against them, and take refuge in Thee from their evils."

You know that we used to perform Tamattu' with the Messenger of Allah (ﷺ), whereupon he said: It is right, but we entertained fear.

“It was said to Ibn ‘Umar: ‘We enter upon our rulers and say one thing, and when we leave we say something else.’ He said: ‘At the time of the Messenger of Allah (ﷺ), we used to regard that as hypocrisy.’”

We were in the company of the Messenger of Allah (ﷺ) when he said. Count for me those who profess al-Islam. We said: Messenger of Allah, do you entertain any fear concerning us and we are (at this time) between six hundred and seven hundred (in strength). He (the Holy Prophet) remarked: You don't perceive; you may be put to some trial, He (the narrator) said: We actually suffered trial so much so that some of our men were constrained to offer their prayers in concealment.

Some people said to Ibn `Umar, "When we enter upon our ruler(s) we say in their praise what is contrary to what we say when we leave them." Ibn `Umar said, "We used to consider this as hypocrisy."
