Hawzah News Agency – The commander of the faithful Imam Ali peace be upon him says: 

إنَّ الحَياءَ والعِفَّةَ مِن خَلائقِ الإيمانِ، وإنّهُما لَسَجِيّةُ الأحْرارِ وشِيمَةُ الأبْرارِ.

'Truly modesty and chastity are of the traits of faith, and they are the attributes of the free and the distinguishing marks of the righteous.'
