Muslim 2192

From Sahih Muslim (Hadith 2192):

Abu Huraira reported Allah's Apostle (ﷺ) as saying:He who offered prayer over the dead, but did not follow the bier, for him is the reward of one qirat, and he who followed it, for him is the reward of two qirats. It was asked what the qirats were. He said: The smaller amongst the two is equivalent to Uhud
