false claim that they are female

وَجَعَلُوا۟ ٱلْمَلَـٰٓئِكَةَ ٱلَّذِينَ هُمْ عِبَـٰدُ ٱلرَّحْمَـٰنِ إِنَـٰثًا ۚ أَشَهِدُوا۟ خَلْقَهُمْ ۚ سَتُكْتَبُ شَهَـٰدَتُهُمْ وَيُسْـَٔلُونَ

They consider the angels- God’s servants- to be female. Did they witness their creation? Their claim will be put on record and they will be questioned about it.

إِنَّ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْـَٔاخِرَةِ لَيُسَمُّونَ ٱلْمَلَـٰٓئِكَةَ تَسْمِيَةَ ٱلْأُنثَىٰ

Those who deny the life to come give the angels female names.
