Al-Ahzab (The Armies of Enemies)

Surah 33 · Verse 32

O wives of the prophet! you are not like any other of the women. If you (wish to) guard (against evil), then do not be soft in your speech (when you talk to other men), lest he in whose heart is a disease, (misunderstandingly) hope, but speak (in) words recognized (as good).

يَا نِسَاءَ النَّبِيِّ لَسْتُنَّ كَأَحَدٍ مِنَ النِّسَاءِ ۚ إِنِ اتَّقَيْتُنَّ فَلَا تَخْضَعْنَ بِالْقَوْلِ فَيَطْمَعَ الَّذِي فِي قَلْبِهِ مَرَضٌ وَقُلْنَ قَوْلًا مَعْرُوفًا
