The Generosity of Hazrat Zubair (radhiyallahu ‘anhu)
Hishaam bin ‘Urwah mentions that seven Sahaabah (radhiyallahu ‘anhum) had appointed Hazrat Zubair (radhiyallahu ‘anhu) as the executor of their estate after their demise. Among these Sahaabah (radhiyallahu ‘anhum) were Hazrat ‘Uthmaan (radhiyallahu ‘anhu), Hazrat ‘Abdur Rahmaan bin ‘Auf (radhiyallahu ‘anhu), Hazrat Miqdaad (radhiyallahu ‘anhu) and Hazrat ‘Abdullah bin Mas‘ood (radhiyallahu ‘anhu). After their demise, he safeguarded their wealth for their children and would spend on them from his own wealth.
