Musnad Ahmad 1180:3

Abu Mu’awiyah narrated to us, Al-A’mash narrated to us, from Shaqiq, from ‘Amr ibn al-Harith ibn al-Mustaliq, from the nephew of Zaynab, the wife of ‘Abdullah, from Zaynab, who said: The Messenger of Allah (peace and blessings of Allah be upon him) addressed us and said: "O assembly of women, give charity, even if it is from your jewelry, for you will be the majority of the people of Hell on the Day of Resurrection." She said: ‘Abdullah was a man of light means, so I said to him: "Ask the Messenger of Allah (peace and blessings of Allah be upon him) for me: Will spending on my husband and orphans who are in my care suffice me as charity?" She said: Awe had been cast upon the Messenger of Allah (peace and blessings of Allah be upon him), so he said: "Go yourself and ask him." She said: So I went, and I reached his door, and there was a woman from the Ansar at the door whose name was Zaynab, and her need was the same as my need. She said: Then Bilal came out to us. She said: We said to him: "Ask the Messenger of Allah (peace and blessings of Allah be upon him) for us: Will spending on our husbands and orphans who are in our care suffice us as charity?" She said: Bilal entered to him and said: "There is a Zaynab at the door." He asked: "Which Zaynab?" She said: He replied: "Zaynab, the wife of ‘Abdullah, and Zaynab, a woman from the Ansar. They are asking you about spending on their husbands and orphans who are in their care; does that suffice them as charity?" She said: He came out to us and said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "They have two rewards: the reward of kinship and the reward of charity."
