I saw As-Sa'ib bin Yazid when he was ninety-four years old, quite strong and of straight figure. Hesaid, "I know that I enjoyed my hearing and seeing powers only because of the invocation of Allah'sApostle . My aunt took me to him and said, 'O Allah's Messenger (ﷺ)! My nephew is sick; will you invokeAllah for him?' So he invoked (Allah) for me."
