Riyad as-Salihin (The Meadows of the Righteous)

by Imam Nawawi

301. Chapter: On the prohibition of affectation, which are words and actions which are without benefit

Allah Almighty says, "Say, 'I do not ask you for any wage for it, for am I a man of false pretensions." (38:86)

1655. Ibn 'Umar said, "We were forbidden affectation." [al-Bukhari]

1656. Masruq said, "We visited 'Abdullah ibn Mas'ud and he said, 'O people! Whoever knows something should say it. Whoever does not know, should say, "Allah knows best." Part of knowledge is that you say about what you do not know, "Allah knows best." Allah Almighty said to His Prophet, may Allah bless him and grant him peace, "Say, 'I do not ask you for any wage for it, for am I a man of false pretensions." (38:86)'" [al-Bukhari]
