Sayyiduna Abu Qatadah (may Allah be pleased with him) narrates: Whenever the Prophet (peace and blessings be upon him) was called to a funeral, he would ask about the (deceased). If he was praised with good, he (peace and blessings be upon him) would lead the funeral prayer over him; and if something other than that (something bad) was said about him, he (peace and blessings be upon him) would say to his family: "You see to his affair," and he (peace and blessings be upon him) would not lead the funeral prayer over him himself. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
