Al-Yasa' (peace be upon him) is mentioned in the Qur'an among the prophets whom Allah guided and favoured. He is named alongside Isma'il, Yunus, and Lut, all of whom Allah preferred above the worlds (6:86).
He is also named with Isma'il and Dhul-Kifl, all counted among the best of people, the chosen (38:48). Beyond these confirmations, the Qur'an does not provide a detailed narrative of his life or mission.
In keeping with authenticity, only what Allah has affirmed is retained: that Al-Yasa' was a guided, chosen, and favoured prophet. Details found in later traditions are unverified and are therefore omitted.
