Musannaf Ibn Abi Shayba 28:1091

Hushaym narrated to us, from Ya'la ibn 'Ata, from 'Umara ibn Hudayr, from Sakhr al-Ghamidi, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "O Allah, bless my nation in their early mornings." He said: And whenever he would send a detachment or an army, he would send them at the beginning of the day. He said: And Sakhr was a merchant man, so he would send his trade at the beginning of the day, and his wealth increased.
