William Muir,
The Caliphate: Its Rise, Decline and Fall…
“ As soon as they had left, the palace gate was barred, and thus for three days and nights the three dead bodies lay in silence solemnly within. Then some chief men of Koreish obtained leave of 'Ali to bury the Caliph's body. In the dusk of evening, the funeral procession wended its way to the burying-ground outside the city. Death had not softened the rebels' hearts, and they pelted the bier with stones. Not in the graveyard, but in a field adjoining, the body, with hurried service, was committed to the dust. ”
