Surat ad-Duha (Arabic: الضحى‎, “The Morning Hours”, “Morning Bright”) is the ninety-third sura of the Qur'an with 11 ayat. This surah is positioned in Para 30 which is also known as Juz Amma (Juz' 30). The Surah takes its name Az-Zuha from the very first word.

Although there is some debate amongst scholars, this sura is often considered to be the second revealed to Muhammad (s). 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 (s) 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 (s) that all will be understood in time. The image of the morning (ad-Dhuha) is the first word of the sorat, and can be understood as symbolizing Muhammad's (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 sorah, the visitations of Gabriel with the words of the Quran would come to Muhammad regularly until his death.
