Dhuha means dawn (day-break), when there becomes brightness in the sky early in the morning. There is a chapter in the Quran called Al-Dhuha. Dhuha (often misspelled Doha) is also a popular girl's name - the Arabic equivalent of the English name Dawn.

In the name of Allah, Most Gracious, Most Merciful

[93.1] I swear by the early hours of the day,
[93.2] And the night when it covers with darkness.
[93.3] Your Lord has not forsaken you, nor has He become displeased,
[93.4] And surely what comes after is better for you than that which has gone befor
[93.5] And soon will your Lord give you so that you shall be well pleased.
[93.6] Did He not find you an orphan and give you shelter?
[93.7] And find you lost (i.e. unrecognized by men) and guide (them to you)?
[93.8] And find you in want and make you to be free from want?
[93.9] Therefore, as for the orphan, do not oppress (him).
[93.10] And as for him who asks, do not chide (him),
[93.11] And as for the favor of your Lord, do announce (it).
