“I was present at the time of the death of one of the sons of Sabur - both being people of merits, piety and great sincerity in their belief. One of them became ill and I think he was Zachariah ibn Sabur. I visited him in his dying condition. He stretched his hand and then said, ‘O Ali, my hands have become white.’ I then visited abu ‘Abd Allah (a.s.), when Muhammad ibn Muslim was also there. When I stood up to leave, thinking that Muhammad would inform him about the case of the man (Zachariah ibn Sabur), he sent someone after me and I returned. He said, ‘Tell me about the man in whose dying condition you were present. What did you hear from him?’ I replied, ‘He stretched his hand and then said, “O Ali, my hands have become white!” Abu ‘Abd Allah (a.s.), then said, ‘By Allah he saw him, by Allah he saw him, by Allah he saw him! ’”
