Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the people complained about Sayyiduna Ali (may Allah be pleased with him). The Messenger of Allah (peace and blessings of Allah be upon him) stood up, delivered a sermon, and also said: "O people! Do not complain about Ali. By Allah! He is above being complained about, for the sake of Allah or in the path of Allah."
