Surah Al-Ahzab 33:32

يَـٰنِسَآءَ ٱلنَّبِىِّ لَسْتُنَّ كَأَحَدٍ مِّنَ ٱلنِّسَآءِ ۚ إِنِ ٱتَّقَيْتُنَّ فَلَا تَخْضَعْنَ بِٱلْقَوْلِ فَيَطْمَعَ ٱلَّذِى فِى قَلْبِهِۦ مَرَضٌ وَقُلْنَ قَوْلًا مَّعْرُوفًا

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], lest he in whose heart is disease should covet, but speak with appropriate speech.

Translation: Saheeh International
