The Book Pertaining to Piety and Softening of Hearts (Kitab Al-Zuhd wa Al-Raqa'iq)

Muslim :: Book 42 : Hadith 7143

Hammam b. al-Harith reported that a person began to praise 'Uthman and Miqdad sat upon his knee; and he was a bulky person and began to throw pebbles upon his (flatterer's) face. Thereupon 'Uthman said: What is the matter with you? And he said: Verily, Allah's Messenger (may peace be upon him) said: When you see those who shower (undue) praise (upon others), throw dust upon their faces.
