Zaynab Thaqafiya reported,

The Messenger of Allah ﷺ said to the women, "Give in charity, even from your jewelry."She said, Abdullah was a man of little means, so she asked him, "Would it be acceptable for me to give my charity to you and to my brother's sons, who are orphans?"Abdullah replied, "Ask the Prophet ﷺ about that."She said, so I went to the Prophet ﷺ, and there at his door was a woman of the Ansar named Zaynab, asking about the very thing I had come to ask about. Bilal came out to us, and we said to him, "Go to the Messenger of Allah ﷺ and ask him about this, but do not tell him who we are."So he went to the Messenger of Allah ﷺ, who asked, "Who are these two?"Bilal answered, "Zaynab."The Prophet ﷺ asked, "Which Zaynab?"Bilal said, "Zaynab the wife of Abdullah, and Zaynab of the Ansar."He said, "Yes. They have two rewards, the reward for kinship and the reward for charity."
