Musnad Ahmad 30:3337

Yazid narrated to us, he said: And Muhammad informed us, from Abu Salamah, from Abu Hurairah, 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. And whoever follows it until its burial is completed, for him are two qirats, one of them—or the smaller of them—is like Uhud." Abu Salamah said: So I mentioned this to Ibn Umar, and he considered it immense. He sent to Aisha, and she said: "Abu Hurairah has spoken the truth." Ibn Umar then said: "We have certainly neglected many qirats."
