Riyad as-Salihin

`Abdullah bin `Umar (May Allah be pleased with them) said: Some people told me, "We visit our rulers and we tell them things contrary to those which we say when we depart from them." `Abdullah bin `Umar (May Allah be pleased with them) replied: "In the era of the Messenger of Allah (ﷺ) we considered this to be an act of hypocrisy."
