'Abdullah bin Mas'ud (May Allah be pleased with him) reported:
I can still recall as if I am seeing the Messenger of Allah ﷺ resembling one of the Prophets whose people scourged him and shed his blood, while he wiped blood from his face, he said: "O Allah! Forgive my people, because they certainly do not know".

[Al-Bukhari and Muslim].

وعن أبي عبد الرحمن عبد الله بن مسعود رضي الله عنه قال: كأني انظر إلى رسول الله ﷺ يحكي نبياً من الأنبياء، صلوات الله وسلامه عليهم، ضربه قومه فأدموه وهو يمسح الدم عن وجهه، يقول :
"اللهم اغفر لقومى فإنهم لا يعلمون" ((متفق عليه)) .
