Satanic Verses
The Satanic Verses incident, known as qissat al-gharaniq (Story of the Cranes), is the name given to the alleged occasion on which the Islamic Prophet Muhammad is said to have mistaken the words of "satanic suggestion" for divine revelation.
Narratives involving these alleged verses can be read in, among other places, the biographies of Muhammad by al-Wāqidī, Ibn Sa'd (who was a scribe of Waqidi) and Ibn Ishaq (as reconstructed by Alfred Guillaume), as well as the tafsir of al-Tabarī. The majority of Muslim scholars however have rejected the historicity of the incident on the bases of their weak isnads (chains of transmission) and the incompatibility of the incident with the theological doctrine of 'isma (Prophetic infallibility, divine protection of Muhammad from mistakes).
The first use of the expression 'Satanic Verses' is attributed to Sir William Muir (1858).

In its essential form, the story reports that Muhammad longed to convert his kinsmen and neighbors of Mecca to Islam. As he was reciting Sūra an-Najm, considered a revelation by the angel Gabriel, Satan tempted him to utter the following lines after verses 19 and 20:
