Surah 15. Al-Hijr, Ayah 91

This, according to the Taj al-'Arus (art. 'adiha and 'adawa) is the meaning of 'idin in the above context: an interpretation also advanced by Tabari and Razi (in the last paragraph of the latter's commentary on this verse). Another interpretation - equally acceptable from the purely linguistic point of view - is "[those] who cut up the Qur'an into separate parts": i.e., accept (on the analogy of the Jews and the Christians) some of it as true and regard the rest as Muhammad's invention. But since - as Tabari points out - those who refuse to believe in the divine origin of the Quran do not accept any of it as true, the first interpretation is by far the preferable.

The Makkan Pagans, in the early days of Islam, in order to dishonour and ridicule the Qur-an, divided what was so far revealed, into bits, and apportioned them to people coming on pilgrimage to Makkah by different routes, slandering and abusing the Prophet of Allah.
