Hadith 6:663
Muhammad ibn Fudayl narrated to us, from Husayn, from Abu Malik, who said: The Messenger of Allah (peace and blessings of Allah be upon him) performed the funeral prayer over Hamzah. Nine [bodies] would be brought and placed alongside him, then he would pray over them, then they would be lifted away and left, and nine others would be brought. He continued to do that until he had prayed over all of them.
حدثنا محمد بن فضيل عن حصين عن أبي مالك قال صلى رسول الله صلى الله عليه وسلم على حمزة فكان يجاء ( ( ( يجاؤ ) ) ) بتسعة فيوضعون معه فيصلي عليهم ثم يرفعون ويترك ويجاء ( ( ( حمزة ) ) ) بتسعة آخرين فلم يزل كذلك حتى صلى عليهم جميعا
