He who follows the bier, for him is the reward of one qirat. Ibn 'Umar said: Abu Huraira narrated it too often. So he sent (a messenger to) 'A'isha to ascertain (the fact). She ('A'isha) testified Abu Huraira. Ibn 'Umar said: We missed so many qirats.
Sahih Muslim Book 11, Hadith 71
← Previous Hadith 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.

Sahih Muslim Book 11, Hadith 70 Next Hadith → He who offers prayer for the dead, for him is (the reward of) one qirat; and he who follows the bier till it is placed in the grave, for him (is the reward of) two qirats. I (Abu Hazim, one of the narrators) said: Abu Huraira, what is a qirat? He said: It is like the hill of Uhud.
