Musannaf Ibn Abi Shayba 21:743

Shu'bah narrated to us, from 'Asim, the freed slave of Quraybah bint 'Abd al-Rahman ibn Abi Bakr, who said: I heard Quraybah narrating from 'Aishah, that she said: "Do not say to the poor person, 'May you be blessed in it,' for he asks both the righteous and the wicked. Rather, say: 'May Allah provide for us and for you.'"
