'Ali b. Abu Talib reported;
There fell to my lot along with Allah's Messenger (may peace be upon him) an
old she-camel from the spoils of Badr. Allah's Messenger (may peace be upon
him) granted me another camel. I made them kneel down one day at the door of an
Ansari, and I wanted to carry on them Idhkhir (a kind of grass) in order to
sell that. There was with me a goldsmith of the tribe of Qainuqa'. I saught to
give a wedding feast (on the occasion of marriage with) Fatima with the help of
that (the price accrued from the sale of this grass). And Hamza b. 'Abd
al-Muttalib was busy in drinking in that house in the company of a singing girl
who was singing to him. She said: Hamza, get up for slaughtering the fat
she-camels.
Hamza attacked them with the sword and cut off their humps and
ripped their haunches, and then took out their livers. I said to Ibn Shihab:
Did he take out anything from the hump? He said: He cut off the humps
altogether. Ibn Shihab reported 'Ali having said: I saw this (horrible) sight
and it shocked me, and I came to Allah's Apostle (may peace be upon him) and
there was Zaid b, Haritha with him and communicated to him this news. He came in
the company of Zaid and I also went along with him and he went to Hamza and he
expressed anger with him. Hamza raised his eyes and said: Are you (not) but the
servants of my father? Allah's Messenger (may peace be upon him) turned back on
his heels (on hearing this) until he went away from them.
