It was narrated from Yahya bin 'Abbad bin 'Abdullah bin Az-Zubair, from his grandfather, that he used to say:

"In the year of Khaibar, the Messenger of Allah 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."

قَالَ الْحَارِثُ بْنُ مِسْكِينٍ قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ وَهْبٍ، قَالَ أَخْبَرَنِي سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ يَحْيَى بْنِ عَبَّادِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنْ جَدِّهِ، أَنَّهُ كَانَ يَقُولُ ضَرَبَ رَسُولُ اللَّهِ ﷺ عَامَ خَيْبَرَ لِلزُّبَيْرِ بْنِ الْعَوَّامِ أَرْبَعَةَ أَسْهُمٍ سَهْمًا لِلزُّبَيْرِ وَسَهْمًا لِذِي الْقُرْبَى لِصَفِيَّةَ بِنْتِ عَبْدِ الْمُطَّلِبِ أُمِّ الزُّبَيْرِ وَسَهْمَيْنِ لِلْفَرَسِ .
