Sunni Scholars hold that the wives of Muhammad were included in the second part of the verse 33:33, since they are addressed in the beginning of verse 33:33. Sunnis reject the notion that the end of this verse would be a stand-alone blessing, meant exclusively for Muhammad, Ali, Fatima, Hasan and Husain, as they have in mind the context of the verse as a whole and the one preceding it.

The Shia counter-argument claims that the verse itself says "only", implying that the blessing of this merit is exclusive to a single group and one other than the wives. i.e., Allah desires to keep away the uncleanness from "only" you, "O people of the House", and not from anyone else, and this is why the six stern commandments of the other verses are given to the wives, because they are not protected and must act accordingly; the "people of the house", on the other hand, need no such instructions. The Shi'a also point out that the rhetoric changes to a masculine tone in the final part of the verse whereas is was feminine before that.

Shias also argue that the first part of the verse addresses a person or group in the feminine gender, while the second part addresses in the masculine gender, meaning that at least one person in the group is a male.

Wilfred Madelung makes the following observation on the verse of purification: "Who are the 'people of the house' here? The pronoun referring to them is in the masculine plural, while the preceding part of the verse is in the feminine plural. This change of gender has evidently contributed to the birth of various accounts of a legendary character, attaching the latter part of the verse to the five People of the Mantle (ahl al-kisā'): Muhammad, 'Ali, Fātima, Hasan and Husayn. In spite of the obvious Shí'ite significance, the great majority of the reports quoted by al-Tabari in his commentary on this verse support this interpretation."
