Sa'id ibn al-Musayyib سعيد بن المسيب بن حزن أبو محمد القرشي · Funerals (Kitab Al-Jana'iz)

(I think that the people of Ziyad informed me that he reported on the authority of the Prophet (ﷺ): A rider should go behind the bier, and those on foot should walk behind it, in front of it, on its right and on its left keeping near it. Prayer should be offered over an abortion and forgiveness and mercy supplicated for its parents.

A negress (or a youth) used to sweep the mosque. The Prophet (ﷺ) missed him, and when he asked about him the people told him that he had died. He said: Why have you not informed me ? He said: Lead me to his grave. So they led him and he prayed over him.

'Uthman said: "or anything added to it." Sulaiman b. Musa said: "or anything written on it." Musaddad did not mention in his version the words "or anything added to it." Abu Dawud said: The word "and that" (wa an) remained hidden to me.
