It was narrated that Zainab, the wife of 'Abdullah, said:

"The Messenger of Allah said to women: 'Give charity, even from women: 'Give charity, even from your jewelry. 'Abdullah was not a wealthy man and she said to him: 'Can I spend my charity on you and on my brother's children who are orphans? 'Abdullah said: 'Ask the Messenger of Allah about that.' She said: So I went to the Messenger of Allah, and at his door I found a woman from among the Ansar who was also called Zainab, and she was asking about the same matter as I was. Bilal came out to us and we said to him: Go to the Messenger of Allah and ask him about that, but do not tell him who we are. He went to the Messenger of Allah and he said:' Who are they?' He said: Zainab.' He said: 'Which Zainab?" He said: 'Zainab Al-Ansariyyah.' Abdullah and Zainab Al-Ansariyyah.' He said: 'Yes, they will have two rewards, the reward for upholding the ties of kinship and the reward dfor giving charity."'
