For women bowed their heads when talking

يَٰنِسَآءَ ٱلنَّبِىِّ لَسْتُنَّ كَأَحَدٍۢ مِّنَ ٱلنِّسَآءِ ۚ إِنِ ٱتَّقَيْتُنَّ فَلَا تَخْضَعْنَ بِٱلْقَوْلِ فَيَطْمَعَ ٱلَّذِى فِى قَلْبِهِۦ مَرَضٌۭ وَقُلْنَ قَوْلًۭا مَّعْرُوفًۭا

O Consorts of the Prophet! Ye are not like any of the (other) women: if ye do fear (Allah), be not too complacent of speech, lest one in whose heart is a disease should be moved with desire: but speak ye a speech (that is) just.
