Isāf (Arabic: إساف) and Nā'ila (Arabic: نائلة) were two deities worshipped as a god and a goddess in pre-Islamic Arabia. They were primarily worshipped by the Quraysh. Some Muslim scholars, including al-Azraqi, claimed that 'Amr ibn Luhayy, the patriarch of the Arab tribe Banu Khuza'a, who introduced idolatry in Mecca, was responsible for the worship of Isāf and Nā'ila. He had called on people to worship them and justified the fact that their ancestors had already done so. The Qurayshi Qusaiy ibn Kilāb had then taken the two stones to the well of Zamzam near the Kaaba. Isāf and Nā'ila were said to be particularly important to the Quraysh tribe, associated with Qurayshi sacrifices involving a talbiya specifically directed to Isāf.
