Musnad Ahmad 27:1845

Ya'la narrated to us, Isma'il narrated to us, from Salim ibn 'Abdullah, from Ibn 'Umar, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever prays over a funeral, for him is a qirat." They said: "O Messenger of Allah, like this qirat of ours?" He said: "No, rather like Uhud, or greater than Uhud."
