Hadith 6574
Sayyiduna Anas (may Allah be pleased with him) narrates: On the occasion of the Battle of Uhud, the Prophet Muhammad (peace be upon him) was wiping blood from his face and saying, "How can a people succeed who wound their Prophet and injure his teeth, while he calls them towards Allah, the Exalted?" Then Allah, the Exalted, revealed this verse: "You have no concern with this matter."
