Does the liver of a camel and its milk invalidate the ablution?

The questioner : Peace be upon you.
O Shaykh, may Allah reward you, O Shaykh: Does the liver of a camel and the milk of a camel invalidate the ablution, just as...?

The Shaykh : Is the question about the liver and not about the milk?

The questioner : Does the milk of a camel invalidate the ablution, just as its meat does?

The Shaykh : It is well known that the Prophet (peace and blessings be upon him) commanded us to perform ablution from the meat of camels. He was asked, "Do we perform ablution from the meat of camels?" and he said: Therefore, every part of the camel invalidates the ablution: the liver, the lungs, the spleen, the intestines, the stomach, and others. As for the milk, some scholars hold that it invalidates the ablution, because the Prophet (peace and blessings be upon him) said: However, most of the scholars who say that the meat of camels invalidates the ablution say that this is on the basis of recommendation. They cite as evidence for this that when the delegation from 'Uraynah or Juhaynah came to the Prophet (peace and blessings be upon him) and they were afflicted by the illness of Medina and complained about it, he said: He did not command them to perform ablution, even though they were newly converted to Islam. They said: So the silence of the Prophet (peace and blessings be upon him) regarding commanding them to perform ablution, despite the high likelihood of ignorance among them, indicates that the milk of camels does not invalidate the ablution. However, if you perform ablution, it is better.
