Sa'id b. al-Musayyib said he prayed behind Abu Huraira at the funeral of a boy who had never sinned and heard him say, “O God, protect him from the punishment in the grave.”
Abu Huraira reported the Prophet as saying in the course of prayer over a dead body, “O God, Thou art its Lord, Thou didst create it, Thou didst guide it to Islam, Thou hast taken its spirit, and Thou knowest best its inner nature and outer aspect. We have come as intercessors, so forgive him.”
Bukhari said without a complete isnad that al-Hasan (i.e. al-Hasan al-Basri (21-110. A.H )) recited Fatihat al-Kitab over an infant and said, “O God, make him for us a righteous deed which has gone before us, a recompense gone ahead, a treasure and a reward.”
Jabir reported the Prophet as saying, “Prayer should not be said over an infant which has not uttered a sound, neither may he inherit nor leave an inheritance.”
Tirmidhi and Ibn Majah transmitted it, but the latter did not mention “nor leave an inheritance”.
