وعن محمد بن زيد
أن ناسًا قالوا لجده عبد الله بن عمر رضي الله عنهما: إنا ندخل على سلاطيننا فنقول لهم بخلاف ما نتكلم إذا خرجنا من عندهم. قال: كنا نعد هذا نفاقًا على عهد رسول الله صلى الله عليه وسلم
Some people said to my grandfather, Abdullah ibn Umar (radiyallahu anhum): We visit our rulers and tell them things contrary to what we say when we leave them. Abdullah ibn Umar (radiyallahu anhum) replied: “In the days of the Messenger of Allah (sallallahu alayhi wa sallam), we counted this act as an act of hypocrisy.”.
