صحيح مسلم

'A'isha, the Mother of the Faithful, reported that Allah's Messenger (ﷺ) said: One who has the longest hands amongst you would meet me most immediately. She farther said: They (the wives of Allah's Messenger) used to measure the hands as to whose hand was the longest and it was the hand of Zainab that was the longest amongst them, as she used to work with her hand and Spend (that income) on charity.
