Abdullah bin Masud reported,

It is as if I can see the Messenger of Allah ﷺ recounting the story of one of the prophets whose people struck him until he bled. He was wiping the blood from his face and saying, "O Allah, forgive my people, for they do not know."

عن عبد الله بن مسعود قال

كأني أنظر إلى رسول الله ﷺ يحكي نبيا من الأنبياء ضربه قومه فأدموه، وهو يمسح الدم عن وجهه ويقول: اللهم اغفر لقومي فإنهم لا يعلمون.
