Hazrat Sakhr (Radi Allahu Anhu) was a very big merchant, and since the Messenger of Allah ﷺ had prayed:

اللَّهُمَّ بَارِكْ لِأُمَّتِي فِي بُكُورِهَا

"O Allah, bless my Ummah in their early mornings."

Therefore, he always used to dispatch his trade goods early in the morning and made a handsome profit.

(Abu Dawud, Kitab al-Jihad, Bab fi al-Ibtikar fi al-Safar)
