Saleh or Salih (صَالِح‎, romanized: Ṣāliḥ, lit. 'Pious') is a Prophet mentioned in the Quran who prophesied to the tribe of Thamud in ancient Arabia, before the lifetime of Prophet Muhammad. The story of Saleh is linked to the story of the She-Camel of God, which was the gift given by God to the people of Thamud when they desired a miracle to confirm that Saleh was truly a prophet.

Shuaib, Shoaib or Shuʿayb (Arabic: شُـعَـيْـب‎, šuʿayb, meaning "who shows the right path"), was an ancient Midianite Nabi (Prophet), sometimes identified with the Biblical Jethro. He is mentioned in the Quran a total of 11 times. He is believed to have lived after Ibrahim (Abraham), and Muslims believe that he was sent as a prophet to a community: the Midianites, who are also known as the Aṣ-ḥāb al-Aykah ("Companions of the Wood"), since they used to worship a large tree.
