From Shakr Al-Ghamidi that the Messenger of Allah ﷺ said: "O Allah bless my Ummah in what they do early (in the day)." He said: "Whenever he ﷺ would dispatch a military expedition or an army, he would send them in the first part of the day." And Sakhr, a man who was a merchant, used to send his goods for trade during the beginning of the day, so he became rich, and his wealth increased. [He said:] There are narrations on this topic from 'Ali, Buraidah, Ibn Mas'ud, Anas, Ibn 'Umar, Ibn 'Abbas, and Jabir.  

قَالَ رَسُولُ اللَّهِ ﷺ اللَّهُمَّ بَارِكْ لأُمَّتِي فِي بُكُورِهَا قَالَ وَكَانَ إِذَا بَعَثَ سَرِيَّةً أَوْ جَيْشًا بَعَثَهُمْ أَوَّلَ النَّهَارِ وَكَانَ صَخْرٌ رَجُلاً تَاجِرًا وَكَانَ إِذَا بَعَثَ تِجَارَةً بَعَثَهُمْ أَوَّلَ النَّهَارِ فَأَثْرَى وَكَثُرَ مَالُهُ قَالَ وَفِي الْبَابِ عَنْ عَلِيٍّ وَابْنِ مَسْعُودٍ وَبُرَيْدَةَ وَأَنَسٍ وَابْنِ عُمَرَ وَابْنِ عَبَّاسٍ وَجَابِرٍ
