Sayyidah Zaynab (may Allah be pleased with her), the wife of Sayyiduna Abdullah (may Allah be pleased with him), narrates: "I had gathered a small amount of my wealth to give in charity, so I came to the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), and said: O Mother of the Believers, I have gathered a small amount of my wealth to give in charity; please ask the Messenger of Allah (peace and blessings be upon him) where I should spend it. In freeing a neck (a slave)? Or in the path of Allah? Or on a husband in hardship and orphaned nephews?" Then the Messenger of Allah (peace and blessings be upon him) came to Sayyidah Aishah (may Allah be pleased with her), and she mentioned this to him (peace and blessings be upon him), and the Messenger of Allah (peace and blessings be upon him) said: "Give it in charity to the husband in hardship and the orphaned nephews, for charity given to a relative doubles the reward."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Zayd bin Abi Unaysah except Khalid bin Abi Yazid."
