Assalamu'alaikum.
There's amazing effects doing Dhuha praying. That's why in SMPIT Baitul Muslim, every students do it by themselves especially before dzikr matsurat at about seven.
God in several verses swear by Dhuha time. In the opening letter Assyams, God says,''By the sun and by the time Dhuha.''In fact, there is a special letter in the Qur'an with Addhuha name.
At the opening, God says,''By the time Duha.''Arrazi Imam explained that God Almighty every swear by something, it shows the great things and great benefits. When God swears by Duha time, mean time Duha is a very important time. True, time Duha is a very important time. Among the Prophet Muhammad's prayer: Allahumma baarik ummatii bukuurihaa fii. That means,''O Allah grant blessing to my people in the morning.''
