What is the ruling on hanging underwear, which has been washed by the domestic workers, outside where everyone can see it?

Modesty (Haya') is a magnificent virtue, beloved by Allah, the Almighty. It prevents indecencies and encourages righteousness and goodness, and it is a part of faith. If there is no modesty, a person may indulge in repulsive acts. Modesty gives rise to the virtue of protective jealousy (Gheerah), which safeguards the heart and limbs from evil and indecencies. Displaying underwear, especially women's underwear, in front of others violates modesty and protective jealousy, and it might embolden those with diseased hearts to harass. Therefore, a Muslim should abstain from such acts and adorn themselves with complete modesty and protective jealousy.
