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

“O wives of the Prophet! You are not like any of the [other] women, provided that you remain [truly] conscious of God. Hence, be not over-soft in your speech, lest any whose heart is diseased should be moved to desire [you]: but, withal, speak in a kindly way.”
