Quran 33:32 — The Parties (Al-Ahzab)

O wives of the prophet, you are not the same as any other women, if you observe righteousness. (You have a greater responsibility.) Therefore, you shall not speak too softly, lest those with disease in their hearts may get the wrong ideas; you shall speak only righteousness.

[33:31] Any one of you who obeys GOD and His messenger, and leads a righteous life, we will grant her double the recompense, and we have prepared for her a generous provision.

[33:33] You shall settle down in your homes, and do not mingle with the people excessively, like you used to do in the old days of ignorance. You shall observe the Contact Prayers (Salat), and give the obligatory charity (Zakat), and obey GOD and His messenger. GOD wishes to remove all unholiness from you, O you who live around the Sacred Shrine, and to purify you completely.
