Du'a al-Sabah (Arabic: دُعاء الصَّباح) (literally the supplication of Sabah, means: orison of the morning) is a prayer advised by the first Imam of the Shiites, Ali ibn Abi Talib, to be recited in the morning.

[8] This prayer was written on the 28th of September in the year 646 (11th of Dhu al-Hijjah in the year 25 AH)[9] by Ali ibn Abi Talib, learned from Muhammad ibn Abdullah, the Prophet of Islam.

[7] Du'a al-Sabah is mentioned by Mohammad-Baqer Majlesi in his books Bihar al-Anwar and Salah.

[5] In a treatise by Yahya ibn Qasim Alavi (seventh century AH), it is claimed that a copy of this prayer was written in Kufic script by Imam Ali himself.

Mohammad-Baqer Majlesi advised to recite this prayer after the dawn salah; Sayyid ibn Baqi also recommends reciting it after the dawn supererogatory salah.
