Musnad Ahmad 1166:16

Ibrahim ibn Khalid narrated to us, he said: Rabah narrated to me, from Ma'mar, from Abu Uthman al-Jahshi, from Musa, or so-and-so son of Abd al-Rahman ibn Abi Rabiah, from Umm Hani, that the Prophet, peace and blessings of Allah be upon him, said to her: "Take sheep, O Umm Hani, for they return in the evening with good, and they go out in the morning with good."
