Refutation of Ibn al-Qayyim’s claim that applying the term “knees” to the joints in the front is a matter of predominance, as it contradicts the texts.

The Shaykh : Here, Ibn al-Qayyim (may Allah have mercy on him) falls into a problem that we have always learned from him to reject. What is the motivation for such an interpretation? He says: If the knee is applied to the joint in the front of the camel, is this a matter of what? Predominance? What does it mean to be a matter of predominance? It means that since people in usage apply the term “knee” to the leg, it was said that the knee in the animal in the front is a matter of what? Predominance. There is no predominance here. This claim is refuted against him linguistically and in Arabic usage. Otherwise, predominance is said, for example, of “the two suns” and “the two moons” and “the two 'Umar” and the like. That is predominance. As for the language, it explicitly states that the camel’s knees are in its front, and Arabic usage and texts are the same. So this claim is refuted because, first, there is no evidence for it, and second, it contradicts the Arabic texts that we mentioned.
He says in the third point: “If it were as they said, he would have said: ‘Let him prostrate as the camel prostrates.’”
This is, of course, according to his previous understanding, where he raises this statement or this possibility that should have been the case. The Messenger forbids prostrating like the prostration of the camel; so how would he say: “Let him prostrate as the camel prostrates”? We say to Ibn al-Qayyim: We agree with you that the Messenger forbade prostrating like the prostration of the camel. So how do you say: “Then let him say: ‘Let him prostrate as the camel prostrates’”? No, but we differ on how the camel prostrates. He says: It prostrates with this falling; meaning it places its head before what? Its middle. No, rather it prostrates by placing its knees before any other part of its body. So the Messenger (peace and blessings be upon him) commanded to go against that. If the Messenger (peace and blessings be upon him) had said: “Let him prostrate as the camel prostrates”... the intention is that a person should not prostrate with the prostration of the camel. Because he mentioned hadiths in which the one praying is forbidden from imitating animals in turning their heads, like the pecking of a crow, and likewise in the prostration of the camel. But the question is: what is the reality of the camel’s prostration? And this reality has become clear, by the permission of Allah.
He said: “And if it were as they said, he would have said: ‘Let him prostrate as the camel prostrates, and the first thing that touches the ground of the camel is its hands.’”
Do you see? The first thing that touches the ground of the camel is its hands. This is wrong, because its hands are always touching the ground. Rather, it is the knees.
He said: “And the secret of the matter is that whoever considers the prostration of the camel, and knows that the Prophet (peace and blessings be upon him) forbade prostrating like the prostration of the camel, knows that the hadith of Wa'il ibn Hujr is the correct one, and Allah knows best.”
So, in summary, Ibn al-Qayyim (may Allah have mercy on him) never imagined the correctness or reality of the camel’s prostration. The proof is that the first thing that falls is its hands, and its hands, like its legs, are always and forever on the ground. Rather, the correct thing is that the first part of its body to fall is the two knees in its front. This is his answer to the conflicting hadith regarding the hadith of Wa'il ibn Hujr, and you have known its weakness.
