Hadith on Nifaq: Hypocrisy to speak two-faced in public and private

Muhammad ibn Zayd reported: Some people said to Ibn Umar, may Allah be pleased with him, “When we had an audience with a ruler, we would speak to them differently than what we said after we left them.” Ibn Umar said, “We used to consider that hypocrisy.”
