Tafsir of As-Saffat 37:150

Or did We create the angels female while they were witnesses! means, how did they decide that the angels are female when they did not witness their creation? This is like the Ayah:

وجعلوا المليكة الذين هم عباد الرحمن إنثا أشهدوا خلقهم ستكتب شهدتهم ويسلون

And they make the angels females who themselves are servants of the Most Gracious. Did they witness their creation Their testimony will be recorded, and they will be questioned! (43:19), which means, they will be questioned about that on the Day of Resurrection
