ad-Duha (Arabic: الضحى‎, “The Morning Hours”, “Morning Bright”) is the ninety-third chapyer (surah) of the Qur'an with 11 verses (ayat). Quran 93 takes its Arabic name from ad-duha, the very first word.

Although there is some debate amongst scholars, this sura is often considered to be the second revealed to Muhammad. After the first sura (al-Alaq) was received, there was a period of silence in which no further messages were revealed. During this time, the new Prophet wondered if he had somehow displeased Almighty Allah, who it seemed for a while was no longer sending down His message. This sura broke that silence, and reassured Muhammad that all will be understood in time. The image of the morning (ad-Dhuha) is the first word of the sura, and can be understood as symbolizing Muhammad's "new day" as the Messenger of God, as well as the "dawn" of the new way of life that would become Islam. After this sura, the visitations of Gabriel with the words of the Qur'an would come to Muhammad regularly until his death.

Because of subject matter, length, style, and placement in the Qur'an, this sura is often coupled with Sura Al-Inshirah. They are generally considered to have been revealed around the same time.
