Musnad Ahmad 4331
sahih

It was narrated that Ibn Mas’ood said:

A man among the Ansar said something objectionable about the Prophet (ﷺ) and I could not refrain from telling the Prophet (ﷺ) about it. I wish that I could have sacrificed all my family and my wealth (rather than have uttered it). He said: "They annoyed Moosa with twore than this and he was patient.” Then he told us that a Prophet was rejected by his people and they wounded him in the head when he brought the message of Allah to them. And he was wiping the blood from his forehead (and saying), O Allah forgive my people for they do not know.
