Hilal bin Yasaf narrated: We came to Sayyiduna Wabisah bin Ma'bad (may Allah be pleased with him), and he was standing leaning on a staff. Someone asked him: What has made you take up a staff? He said: Sayyidah Umm Qays bint Mihsan (may Allah be pleased with her) told me that when the Messenger of Allah (peace and blessings be upon him) grew old and his body became heavy, he (peace and blessings be upon him) began to lean on a staff.
