The Messenger of Allah ﷺ said to the women, "Give in charity, even from your jewelry."She said, 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 Messenger of Allah ﷺ about that."She said, So I went to the Prophet ﷺ, and at his door I found a woman from the Ansar called Zaynab who was asking 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."So he went to the Messenger of Allah ﷺ, who asked, "Who are they?"Bilal said, "Zaynab."He asked, "Which Zaynab?"Bilal said, "Zaynab the wife of Abdullah, and Zaynab of the Ansar."He said, "Yes. They will have two rewards, the reward for kinship and the reward for charity."
أخبرنا بشر بن خالد قال حدثنا غندر عن شعبة عن سليمان عن أبي وائل عن عمرو بن الحارث
قال رسول الله ﷺ للنساء تصدقن ولو من حليكن قالت وكان عبد الله خفيف ذات اليد فقالت له أيسعني أن أضع صدقتي فيك وفي بني أخ لي يتامى فقال عبد الله سلي عن ذلك رسول الله ﷺ قالت فأتيت النبي ﷺ فإذا على بابه امرأة من الأنصار يقال لها زينب تسأل عما أسأل عنه فخرج إلينا بلال فقلنا له انطلق إلى رسول الله ﷺ فسله عن ذلك ولا تخبره من نحن فانطلق إلى رسول الله ﷺ فقال من هما قال زينب قال أي الزيانب قال زينب امرأة عبد الله وزينب الأنصارية قال نعم لهما أجران أجر القرابة وأجر الصدقة
