Another example: "Al-'Alim" is one of the names of Allah, encompassing complete knowledge, which was not preceded by ignorance and is not followed by forgetfulness.

The Shaykh :"And another example:" Al-'Alim "is one of the names of Allah the Exalted" What is the evidence?
The student: ... .

The Shaykh : What?
The student: ... .

The Shaykh : Is Al-'Alim unrestricted?
The student: .

The Shaykh : Perfect, and it is abundant. Al-'Alim is one of the names of Allah. The scholars of usul al-fiqh (the principles of jurisprudence) said: "Knowledge is perceiving the known as it is." If you wish, say: perceiving a thing as it is, with a firm perception that corresponds to reality. Do you understand? Good. One who does not perceive the thing at all is what? Ignorant. This is called simple ignorance. And one who perceives it without firmness, but with possibility, is either one who has a conjecture, one who is in doubt, or one who is mistaken. I hope you pay attention. If he does not perceive it with firm perception, he is what? Either one who has a conjecture, one who is in doubt, or one who is mistaken. How is this division? If he does not perceive it with firm perception, but it is more likely in his conjecture that the matter is so, then we say this is conjecture because there is a possibility that it is not.
The opposite of conjecture is delusion. The weaker side is called delusion. If it is equal, it is doubt. This is the division of the jurists. As for in the Shari'ah, the matter is either doubt or certainty; there is no detail. Do you understand? Good. Firm perception that corresponds to reality, to avoid compound ignorance. Compound ignorance is perceiving the thing, but not in accordance with reality.
Let us give an example of this. If a questioner is asked: When was the Battle of Badr?
He answered: It was in the fourth year of the Hijrah. This is not knowledge; rather, it is compound ignorance.
Good. And if he says: I do not know, this is not knowledge, but it is simple.
And if he says: I do not know, is it in the second year or the fourth? This is doubt.
And if he says: I do not know, is it in the second year or the fourth, and it is more likely in my conjecture that it is in the fourth? This is conjecture, and the weaker side is delusion.
Allah, Mighty and Majestic, His knowledge encompasses everything. Therefore, it encompasses complete knowledge that was not preceded by ignorance and is not followed by forgetfulness. Let us look at our knowledge, O brothers. Our knowledge is preceded by ignorance. Say, O my brother? Preceded by ignorance? What made you perceive this? I mean, what is the evidence first? What is the evidence that our knowledge is preceded by ignorance?
The student: ... .

The Shaykh : Yes, no mistake.
Likewise, it is followed by forgetfulness. What is the evidence? Brother?
The student: ... .

The Shaykh : No. And it did not say "and he did not find for it knowledge." Forgetfulness here means leaving. Who recalls this?
The student: The story of Musa with al-Khidr. The statement of the companion of Musa's boy:

The Shaykh : Where are you going to the story of Musa? You have something closer than this. Glory be to Allah. Sometimes a person says, if he looks for something and does not find it, then it falls to him without seeking. Good. If we know that our knowledge is preceded by ignorance and followed by forgetfulness.
