وَثِيَابَكَ فَطَهِّرۡ
and purify your clothes,
Agha Ali Puya Commentary
Commentary on Quran 74:4
[Pooya/Ali Commentary 74:4] In the light of the commentary of Baqarah: 187 (They are your dress and you are theirs), some commentators say that thiyab means his wives. Some commentators say that these verses refer to the dirt and filth which the pagans used to throw at the Holy Prophet. Aqa Mahdi Puya says: Thiyab literally means a cloth which covers the body, but as interpreted by the Ahl ul Bayt, it is used here to point out the nature, attributes and style which surround the inner self, and also the external environment in which a man lives.
