" is a tool of restriction, and the scholars say that restriction means affirming the ruling for what is mentioned and negating it for everything else. The restriction here is relative. Is it real or relative? Real or not relative? The division is four: either relative, or real, or both, or neither.
The student: ...
The Shaykh : Why is it relative?
The student: ...

The Shaykh : Because Allah wants this and other things. The relative is that which is not restricted in reality to this thing, and the real is that which is restricted in reality to this thing. So if I say, "No student pays attention except Khalid," what happens? Is it real or relative? We see: if there is no one else, it is real; if someone else pays attention, it is relative.
The student: ...?

The Shaykh : ... The relative is like this man, for example, who pays attention so much that no one else pays attention, as if I said, "No brave man except Khalid," meaning Khalid ibn al-Walid. Yes, "No brave man except Khalid." What do you say, is it real or relative? No, it is not real, because there are many brave men other than Khalid ibn al-Walid. Yes, "No seal of the prophets except Muhammad (peace and blessings be upon him)." This is real, because there is no seal of the prophets except Muhammad, the Messenger of Allah. Clear? Good. Here, Does Allah the Mighty and Majestic not want for the People of the House except that? The answer is: Allah wants to remove impurity from them and purify them, and to bestow blessings upon them, and to shower them with favor, and so on. And His saying: Is the will here legislative or cosmic? The will is cosmic. Yes, and this is the benefit of the exclusivity of the People of the House for that. As for the will to remove impurity, it is for everyone from the legislative side. And the will, as we have mentioned before, is of two types: legislative and cosmic. Are they concomitant? No, one may exist without the other, and they may coexist. So what is the difference between them so that we know their coexistence and separation?
First: The cosmic will relates to what Allah loves and what He does not love; this is one. The legislative will relates only to what Allah loves. So if I say: meaning legislatively, it means He loves it.
Second: The cosmic will necessitates the occurrence of the intended thing, and the legislative will does not necessitate the occurrence of the intended thing. So the difference is from two aspects. We now look: the two wills may coexist in something, or both may be absent, or one may exist without the other.
