As for the Verse of Purification, it does not state that the People of the House are pure and that impurity has been removed from them. Rather, it commands them to do what brings about their purification and the removal of impurity from them.
For His words:
“Allah only intends to remove impurity from you, O People of the House, and to purify you completely.”
[Surah al-Ahzāb: 33]
are like His words, Exalted is He:
“Allah does not intend to place any hardship upon you, but He intends to purify you.”
[Surah al-Mā’idah: 6]
And His words:
“Allah intends to make matters clear to you, guide you to the ways of those who came before you, and turn to you in mercy. Allah is All-Knowing, All-Wise. Allah intends to turn to you in mercy, while those who follow their desires want you to deviate greatly. Allah intends to lighten your burdens, for the human being was created weak.”
[Surah al-Nisā’: 26–28]
Thus, the intent here encompasses command, love, and approval (1); it is not the will that necessarily entails the occurrence of what is willed. Were that the case, everyone whom Allah intended to purify would have become pure (2). This interpretation is all the more consistent with the position of these Qadarī Shi'a, for according to them Allah wills what does not occur, while what He does not will occurs.
Thus, His words:
“Allah only intends to remove impurity from you, O People of the House, and to purify you completely,”
if this purification comes about by performing what is commanded and refraining from what is prohibited, then (3) it depends upon their will and their deeds: if they do what they have been commanded, they are purified; otherwise, they are not.
They say that Allah does not create their deeds and is unable to purify them (4) or remove impurity from them (5). Those who affirm the divine decree, however, say that Allah is capable of doing so (6),
