On the issue of prostrating like a camel, and that the camel's knees are in its front.

The Shaykh : Listen to what he says at the end of the second page. He says: "As for the reports preserved from the Companions, the preserved one—meaning the established one in the authentic collections—from 'Umar ibn al-Khattab (may Allah be pleased with him) is that he used to place his knees before his hands." 'Abd al-Razzaq, Ibn al-Mundhir, and others mentioned this from him. It is also the report from Ibn Mas'ud (may Allah be pleased with him). Al-Tahawi mentioned it from Fahd from 'Umar ibn Hafs from his father from al-A'mash from Ibrahim from the companions of 'Abdullah, 'Uqbah and al-Aswad, who said: "We preserved—pay attention here—we preserved from 'Umar in his prayer that he would fall after his bowing onto his knees, just as a camel falls."
This is the text of Ibn al-Qayyim himself saying: "He fell onto his knees just as a camel falls." So how does a camel fall? Onto its knees. He says there that this is an unknown usage in the Arabic language. So now we have two texts, up to now, not stated in... that the camel's knees are in its front. We now have two texts. One is what he cited, and it is an argument against him. He cited it to prove that 'Umar ibn al-Khattab would kneel on his knees, he would... on his knees. And he did not notice—may Allah have mercy on him—and this is the nature of the person who has not written... that in this very narration he is using as evidence for his school, from one angle, he did not notice that from another angle it demolishes what he said, namely that the language does not know that a camel falls onto its knees; that is: onto its front; onto its knees which are in its front. So then... what concerns the claim that the language does not know is refuted in many and very many ways. He said: "And the knee is in the legs; we placed it in the legs for the sake of analogy regarding the human being. As for the animal, no. And if the name 'knee' is applied to the two in the hands, it is by way of predominance."
