It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that a young man passed by Sayyiduna Umar (may Allah be pleased with him), and Umar (may Allah be pleased with him) said: "What a fine young man he is!" Sayyiduna Abu Dharr (may Allah be pleased with him) followed that young man and said: O young man, ask forgiveness for me. He asked in astonishment: O Abu Dharr, shall I pray for you when you are a Companion of the Messenger of Allah (peace and blessings be upon him)? He said: Yes! (Pray for me.) He said: I will not pray until you tell me the reason. Sayyiduna Abu Dharr (may Allah be pleased with him) said: You passed by Umar and he said about you: "What a fine young man he is!" And indeed I heard the Messenger of Allah (peace and blessings be upon him) saying: "Indeed, Allah Almighty has placed the truth upon the tongue and heart of Umar." This hadith is sahih (authentic) on the condition of Imam Muslim, but they did not record it with this wording (context).
