عَنْ صَخْرٍ الْغَامِدِيِّ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: اللَّهُمَّ بَارِكْ لِأُمَّتِي فِي بُكُورِهَا ، وَكَانَ إِذَا بَعَثَ سَرِيَّةً أَوْ جَيْشًا بَعَثَهُمْ فِي أَوَّلِ النَّهَارِ، وَكَانَ صَخْرٌ رَجُلًا تَاجِرًا وَكَانَ يَبْعَثُ تِجَارَتَهُ مِنْ أَوَّلِ النَّهَارِ فَأَثْرَى وَكَثُرَ مَالُهُ (ابو داؤد : ۲۶۰۶)
Translation : Hazrat Sakhr Ghamidi (may Allah be pleased with him) states that the Prophet (PBUH) said: "O Allah! Put blessing for my Ummah in their mornings." Therefore, whenever He (PBUH) had to dispatch an expedition or an army, He would dispatch them in the first part of the day. And Hazrat Sakhr (may Allah be pleased with him) was a merchant companion, so he used to send his workers in the first part of the day, thus he became wealthy and his wealth increased abundantly.
