Surah 43. Az-Zukhruf, Ayah 16

It should be remembered that the people thus addressed were the pagan Arabs, who believed that some of their goddesses, as well as the angels, were "God's daughters". In view of the fact that those pre-Islamic Arabs regarded daughters as a mere liability and their birth as a disgrace, this verse is obviously ironical. (Cf. in this connection {16:57-59}.)

To imagine goddesses (female gods) or mothers or daughters to Allah was particularly blasphemous in the mouths of people who held the female sex in contempt. Such were the pagan Arabs, and such (it is to be feared) are some of the moderns. They wince when a daughter is born to them and hanker after sons. With that mentality, how can they attribute daughters to Allah?
