Musnad Ahmad

It is narrated from Sayyiduna Sakhr Ghamidi that the Prophet (peace be upon him) used to supplicate: "O Allah, bless my Ummah in their early hours." The Prophet (peace be upon him), whenever he sent out an army, would send it at the beginning of the day. The narrator of the hadith, Sayyiduna Sakhr, was a merchant; he also used to send his workers early in the morning, and as a result, he became very wealthy.
