Sayyiduna Abu Barzah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) had nine wives. He said: The best of you is the one whose hand is the longest. Each one of them stood up and measured her hand by placing it on the wall. The Prophet (peace and blessings be upon him) said: I did not mean this; rather, I meant the one who does the most work with her two hands (and gives the earnings in charity).
Abu Ya'la recorded it, and its chain is hasan (good).
This report is strengthened by the report that will come next.
