The Book of Etiquette of Traveling

The Messenger of Allah (peace be upon him) said, "O Allah! Bless my people in the early part of the day (morning). Whenever he dispatched a detachment or an army-unit, he would dispatch it at the beginning of the day (soon after dawn). The narrator, Sakhr (May Allah be pleased with him) was a merchant, and he used to send off his merchandise at the beginning of the day. So his trade flourished and he made a good fortune.
