Hadith 3975
Chapter 12: Restraining one's tongue during times of tribulation - كتاب الفتن
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا خَالِي، يَعْلَى عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ أَبِي الشَّعْثَاءِ، قَالَ قِيلَ لاِبْنِ عُمَرَ إِنَّا نَدْخُلُ عَلَى أُمَرَائِنَا فَنَقُولُ الْقَوْلَ فَإِذَا خَرَجْنَا قُلْنَا غَيْرَهُ . قَالَ كُنَّا نَعُدُّ ذَلِكَ عَلَى عَهْدِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ النِّفَاقَ .
It was narrated that Abu Sha’tha said:
“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.’”
