32nd Ayah from Surah Al Ahzab
Sahih International
O wives of the Prophet, you are not like anyone among women. If you fear Allah, then do not be soft in speech [to men], lest he in whose heart is disease should covet, but speak with appropriate speech.
Abdul Haleem
Wives of the Prophet, you are not like any other woman. If you are truly mindful of God, do not speak too softly in case the sick at heart should lust after you, but speak in an appropriate manner;
Mohsin Khan/Hilali
O wives of the Prophet! You are not like any other women. If you keep your duty (to Allah), then be not soft in speech, lest he in whose heart is a disease (of hypocrisy, or evil desire for adultery, etc.) should be moved with desire, but speak in an honourable manner.
Taqi Usmani
O wives of the prophet, you are not like any other women, if you observe taqwā (righteousness). So, do not be too soft in your speech, lest someone having disease in his heart should develop fancies (about you); and do speak with appropriate words.
Pickthall
O ye wives of the Prophet! Ye are not like any other women. If ye keep your duty (to Allah), then be not soft of speech, lest he in whose heart is a disease aspire (to you), but utter customary speech.
Pickthall
O Consorts of the Prophet! Ye are not like any of the (other) women: if ye do fear (Allah), be not too complacent of speech, lest one in whose heart is a disease should be moved with desire: but speak ye a speech (that is) just.
