The Messenger of Allah ﷺ said to the women, "Give in charity, even from your jewelry."She said that Abdullah was a man of modest means, so she asked him, "Would it be acceptable for me to give my charity to you and to my orphaned nephews?"Abdullah replied, "Ask the Prophet ﷺ about that."She said, "So I went to the Prophet ﷺ, and at his door I found a woman of the Ansar named Zaynab, who had come to ask about the very same matter. 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.'"Bilal went in to the Messenger of Allah ﷺ, who asked, "Who are they?"Bilal answered, "Zaynab."He asked, "Which Zaynab?"Bilal said, "Zaynab the wife of Abdullah, and Zaynab the Ansari woman."He said, "Yes. They will have two rewards, the reward of upholding kinship ties and the reward of charity."
قال حدثنا محمد بن جعفر قال حدثنا شعبة عن سليمان عن أبي وائل عن عمرو بن الحارث
قال رسول الله ﷺ للنساء تصدقن ولو من حليكن قالت فكان عبد الله خفيف ذات اليد فقالت له أيسعني أن أضع صدقتي فيك وفي بني أخي أو بني أخ لي يتامى فقال عبد الله سلي عن ذلك النبي ﷺ قالت فأتيت النبي ﷺ فإذا على بابه امرأة من الأنصار يقال لها زينب تسأل عما أسأل عنه فخرج إلينا بلال فقلنا انطلق إلى رسول الله ﷺ فسله عن ذلك ولا تخبر من نحن فانطلق إلى رسول الله ﷺ فقال من هما فقال زينب فقال أي الزيانب فقال زينب امرأة عبد الله وزينب الأنصارية فقال نعم لهما أجران أجر القرابة وأجر الصدقة
