Jami` at-Tirmidhi 3003

Narrated Anas:"The face of the Messenger of Allah (ﷺ) was wounded, his incisors were broken, and he was struck by an arrow on his shoulder. While blood was flowing over his face and he was wiping it, he said: 'How can a nation succeed while they are doing this to their Prophet and he is calling them to Allah?' So Allah, Most High revealed: Not for you is the decision; whether He turns in mercy towards them or punishes them; verily they are the wrongdoers (3:)
