The Quran

وَجَعَلُوا المَلائِكَةَ الَّذينَ هُم عِبادُ الرَّحمٰنِ إِناثًا ۚ أَشَهِدوا خَلقَهُم ۚ سَتُكتَبُ شَهادَتُهُم وَيُسأَلونَ

Muhammad Asad

And [yet] they claim that the angels - who in themselves are but beings created by the Most Gracious¹ - are females: [but] did they witness their creation? This false claim of theirs² will be recorded, and they will be called to account [for it on Judgment Day]!

Or: "who are but worshippers [or "creatures"] ('ibad) of the Most Gracious" - in either case stressing their having been created and, hence, not being divine.
Lit., "their testimony", i.e., regarding the "sex" of the angels, who are spiritual in nature (Razi) and, therefore, sexless.
