Quran 33:32 from Surah Al-Ahzaab on Divine Marvels.
يَٰنِسَآءَ ٱلنَّبِيِّ لَسۡتُنَّ كَأَحَدٖ مِّنَ ٱلنِّسَآءِ إِنِ ٱتَّقَيۡتُنَّۚ فَلَا تَخۡضَعۡنَ بِٱلۡقَوۡلِ فَيَطۡمَعَ ٱلَّذِي فِي قَلۡبِهِۦ مَرَضٞ وَقُلۡنَ قَوۡلٗا مَّعۡرُوفٗا
English translation: O wives (of) the Prophet! You are not like anyone among the women If you fear (Allah) then (do) not be soft in speech lest should be moved with desire he who in his heart (is) a disease but say a word appropriate
Transliteration: yanisaa al-nabiyi lastunna ka-ahadin mina al-nisai ini ittaqaytunna fala takhda'na bil-qawli fayatma'a alladhi fi qalbihi maradun waqul'na qawlan ma'rufan
