Fa'too bikitabikum in kuntum sadiqeen (surah Assaaffat: 157)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(37:157) Bring your Book, if you are truthful. *88

Faatoo bi Kitaabikum in kuntum saadiqeen

*88) That is, "There can be only two bases for regarding the angels as the daughters of Allah: Either such a thing could be said on the basis of observation, or the one who asserted it should possess a Divine book in which Allah Himself might have stated that the angels were His daughters. Now, if those who held such belief could neither make a claim to have observed such a thing nor did they possess any divine book that might contain such a thing, there could be no greater stupidity than this that one should base one's religious belief on mere conjecture, and attribute to AIlah, Lord of the worlds, such things as were patently ridiculous.
