Mas'ud bin al-Hakam al-Ansari informed Nafi' that he had heard Hadrat 'Ali (RA) , son of Abu Talib, say about the biers: Verily, the Holy Prophet (ﷺ) used to stand first but later on kept sitting; but it is also narrated that Nafi' ibn Jubair saw Waqid bin 'Amr standing for a bier till it was placed down.
