Surah 21. Al-Anbiya, Ayah 26

I.e., utterly remote from the imperfection implied in the concept of "offspring": see note [77] on 19:92 .

This alludes to prophets like Jesus, whom the Christians regard as "the son of God", as well as to the angels, whom the pre-Islamic Arabs considered to be "God's daughters" (since they were conceived of as females).

 Some pagans claimed that the angels are Allah’s daughters.

This refers both to the Trinitarian superstition that Allah has begotten a son, and to the Arab superstition that the angels were daughters of Allah. All such superstitions are derogatory to the glory of Allah. The prophets and the angels are no more than servants of Allah: they are raised high in honour, and therefore they deserve our highest respect, but not our worship.
