Musnad Ahmad 122:2

'Affan narrated to us, Shu'bah narrated to us, he said: Ya'la ibn 'Ata' informed me, he said: I heard 'Amarah ibn Hadid—a man from Bajilah—say: I heard Sakhr al-Ghamidi—a man from Azd—say that the Prophet, peace and blessings of Allah be upon him, said: "O Allah, bless my nation in their early mornings." He said: And the Messenger of Allah, peace and blessings of Allah be upon him, whenever he sent a military detachment, he would send them at the beginning of the day. And Sakhr was a merchant man, and he had servants, so he would send his servants at the beginning of the day. He said: So his wealth increased until he did not know where to put it.
