quran:37:49 –

As if they were ˹delicate˺ eggs, well-protected.  

as if they were, in terms of ˹the starkness of their white˺ colour, hidden eggs, of ostriches, sheltered by their feathers from dust, the colour being that whiteness with a hint of pallor, which is the most beautiful of female complexions.
القرآن:٣٧:٤٩ –

كَأَنَّهُنَّ بَيْضٌ مَكْنُونٌ  

{كأنهن} في اللون {بيض} للنعام {مكنون} مستور بريشه لا يصل إليه غبار، ولونه وهو البياض في صفرة، أحسن ألوان النساء.
