Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates: On the occasion of the Farewell Pilgrimage, the Prophet (peace and blessings be upon him) said: "May Allah Almighty keep radiant the person who hears my words and retains them, for sometimes a person who carries knowledge is not himself a scholar. There are three things about which the heart of a believer does not harbour rancour: making one's deeds sincerely for Allah Almighty, sincere goodwill towards the Muslim rulers, and keeping to the community of the Muslims, for their supplication encompasses those who are behind them (that is, those who are not with them)."
Al-Bazzar recorded it, and its narrators have been declared trustworthy, except if the teacher of Sulayman bin Sayf is Sa'id bin Bazigh, for I have not seen anyone mention him; and if he is Sa'id bin al-Rabi', then he is among the narrators of the Sahih, for he (Sulayman) narrated from both of them. And Allah knows best.
