It was narrated from Ya bin ‘Abbad bin ‘Abdullah bin Az-
Zubair, from his grandfather, that he used to say: “In the year of Khaibar, the Messenger of Allah صلی اللہ علیہ وآلہ وسلم
allocated four shares to Az-Zubair bin Al-’Awwam: A share of
Az-Zubair, a share for the relatives of Safiyyah bint ‘Abdul-Muttalib, the mother of Az-Zubair, and two shares for the horse.” (Sahih)
