Ad-Dukhan (Arabic: الدخان, ad-dukhān; meaning: Smoke) is the 44th chapter (surah) of the Quran with 59 verses (ayat). The word dukhan, meaning 'smoke', is mentioned in verse 10.

Verse 37 mentions the people of Tubba, interpreters explain that this refers to the people of Sheba.

Regarding the timing and contextual background of the believed revelation (asbāb al-nuzūl), it is an earlier "Meccan surah", which means it is believed to have been revealed in Mecca, rather than later in Medina.
