The Messenger of Allah ﷺ said, "O Allah, bless my nation in its early mornings."Whenever he sent out an expedition or an army, he would dispatch them at the beginning of the day. Sakhr was a merchant, and he used to send out his trade goods at the beginning of the day, so he prospered and his wealth grew abundant.
حدثنا أبو بكر بن أبي شيبة حدثنا هشيم عن يعلى بن عطاء عن عمارة بن حديد
قال رسول الله ﷺ اللهم بارك لأمتي في بكورها قال وكان إذا بعث سرية أو جيشا بعثهم في أول النهار قال وكان صخر رجلا تاجرا فكان يبعث تجارته في أول النهار فأثرى وكثر ماله
