Surah 13. Ar-Ra'd, Ayah 39

I.e., He is the fountainhead or source (asl) of all revelation. - As regards the preceding reference to the abrogation of earlier divine dispensations and their supersession by later ones - ending with the final revelation, the Qur'an - see 2:106 and the corresponding note [87]. (According to Qatadah, as quoted by Tabari and Ibn Kathir, the passage under consideration has the same purport as 2:106 .)
