The Shaykh's discussion with the students regarding this hadith.

The Shaykh : May Allah send blessings and peace upon him.
Yes, we first discussed his saying in terms of its grammar, and in terms of the giver: who gave? Allah. Good. And we discussed his saying and we said that fear in the enemy is the greatest of weapons, because when fear settles in the enemy's heart, he cannot resist or stand against his enemy; he cannot, he flees. Good. And He made the earth a place of prostration and a place of purification for me. We explained who the Maker is? Allah (Mighty and Majestic). And we explained in the past that the making is both cosmic and legislative, and we gave examples of that. ... An example of cosmic making, my brother? Did you not attend?
The student: ...

The Shaykh : Yes, the one after you. And you did not attend, there is no power nor strength except by Allah. Yes, His saying (Glorified and Exalted is He)
The student: ...

The Shaykh : This is cosmic making. Good, well done. And what is the example of legislative making?
The student: ...

The Shaykh : Well done. That is, what legislated these things? If someone said to you that the making here is a making ... in the sense of cosmic making?
The student: ...

The Shaykh : It is not correct. Why? Because it has become [a fact] and its negation is not correct, meaning it was made cosmically and its negation is not correct. Good, rest. And his saying (peace and blessings be upon him) meaning a place for prostration. And we mentioned yesterday that the term "mosque" is used for two meanings.
One of them is what it is valid to prostrate in.
And the second is what was made a specific place for prostration. Is that not so? So the building that people frequent and pray in is a specific mosque, and the entire earth is a general mosque, all of it is suitable for prostration in it. Good. And we discussed the word "purification" and we said that the intended meaning of "purification" (tahir) is that by which one purifies oneself, and "purification" (tuhur) is the act. And the brother will give us an example. Did you not attend? Please.
The student: ...

The Shaykh : No, we want "tahir" and "tuhur". Come on, good.
The student: ...

The Shaykh : I bought you a "tahir", meaning water by which you purify yourself. Good, this is "tahir" in the sense of that by which one purifies oneself. And "tuhur"? I liked "tuhur" of so-and-so, meaning his purification. And from that is the hadith of A'ishah . Good, good. And we explained that "earth" is a general word that includes all types of earth: sand, stone, soil, clay, and others; it is general. He made the earth for me. Did you understand or not? Good .
