The Messenger of Allah ﷺ said, "Whoever prays over a funeral receives one qirat, and whoever follows it until the burial is completed receives two qirats, one of them," or "the smaller of them, is like Mount Uhud."I mentioned this to Ibn Umar, so he sent word to Ayesha and asked her about it.She replied, "Abu Hurairah has spoken the truth."Ibn Umar then said, "We have indeed missed out on many qirats."
حدثنا أبو كريب حدثنا عبدة بن سليمان عن محمد بن عمرو حدثنا أبو سلمة
قال رسول الله ﷺ من صلى على جنازة فله قيراط ومن تبعها حتى يقضى دفنها فله قيراطان أحدهما أو أصغرهما مثل أحد فذكرت ذلك لابن عمر فأرسل إلى عائشة فسألها عن ذلك فقالت صدق أبو هريرة فقال ابن عمر لقد فرطنا في قراريط كثيرة
