Narrated 'Ali:
I got an old she-camel as my share from the booty, and the Prophet had given me another from Al-Khumus. And when I intended to marry Fatima (daughter of the Prophet), I arranged that a goldsmith from the tribe of Bani Qainuqa' would accompany me in order to bring Idhkhir and then sell it to the goldsmiths and use its price for my marriage banquet.
