Qur'an 33:32 · Al-Ahzaab

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

(32) O wives of the Prophet, you are not like anyone among women. If you fear Allāh, then do not be soft in speech [to men],[1195] lest he in whose heart is disease should covet, but speak with appropriate speech.
