It is narrated from Sayyiduna Abu Barzah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) had nine wives. One day he (peace and blessings be upon him) said: "The best of you is the one whose hand is the longest." So each of them began placing her hand on the wall (to measure it), whereupon he (peace and blessings be upon him) said: "I did not mean this (physical length); rather (I meant) the one of you who does the most work with her hands (charity and labour)."
