O Allah, bless the early morning hours for my Ummah
Authentic hadithعن صَخْر بن وَدَاعَة الغامدي رضي الله عنه عن النبي صلى الله عليه وسلم قال: «اللهم بارك لأمتي في بُكُورها» وكان إذا بعَث سَرِيَّةً أو جيشًا بعَثَهم من أوَّل النهار، وكان صَخْر تاجرًا، وكان يبعث تِجارته أوَّل النهار، فأَثْرَى وكثُر مالُه.
Sakhr ibn Wadā‘ah al-Ghāmidi (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "O Allah, bless the early morning hours for my Ummah." Whenever the Prophet (may Allah's peace and blessings be upon him) sent a detachment or an army, he would send them at the early morning time. Sakhr was a merchant, and he used to send his merchandise at the early morning time, so he became rich and his wealth grew.
Explanation
The Prophet (may Allah's peace and blessings be upon him) supplicated for his Ummah by asking Allah, the Almighty, to bless their early morning hours for them, so that this time would be enough to get their daily work done and their work itself would be blessed. This blessing includes seeking sustenance, knowledge, victory over the enemy, or any other act. This is why the Prophet (may Allah's peace and blessings be upon him) used to send his army in the early morning. Similarly, Sakhr ibn Wadā‘ah (may Allah be pleased with him) became a wealthy man because of the supplication of the Prophet (may Allah's peace and blessings be upon him).
