It is narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Soon people will come to you seeking (religious) knowledge; so when they come to you, accept my counsel to treat them well (that is, treat them kindly)."
No one narrated this hadith from Imran al-Qattan (may Allah have mercy on him) except Yahya bin Sakan (may Allah have mercy on him), and Yazid bin Hakim (may Allah have mercy on him) is alone in narrating it.
It is like this in the Dar al-Haramayn edition, and the correct name is probably (Ibn Abi Hakim).
