A man began praising Uthman, so Miqdad, who was a large man, knelt down on his knees and started throwing pebbles into his face.Uthman asked him, "What is the matter with you?"He replied, "The Messenger of Allah ﷺ said, 'When you see those who heap praise, throw dirt in their faces.'"

عن همام بن الحارث

أن رجلا جعل يمدح عثمان، فعمد المقداد، فجثا على ركبتيه- وكان رجلا ضخما- فجعل يحثو في وجهه الحصباء، فقال له عثمان: ما شأنك؟ فقال: إن رسول الله ﷺ قال: إذا رأيتم المداحين فاحثوا في وجوههم التراب.

His saying, "Those who avoid the major sins and immoralities, except for minor lapses. Indeed, your Lord is Wasi in forgiveness. He knows best about you when He produced you from the earth and when you were fetuses in the wombs of your mothers. So do not claim purity for yourselves. He knows best who has attained taqwa."
