The ruling on a dog's saliva and the use of soap in purification
Machine translationRead the Arabic original
The questioner:
It is not considered impure unless it is changed by the impurity,
The Shaykh:
as mentioned in the preceding hadiths. For this reason, if a dog drinks from a vessel, the vessel should be washed; because a dog's saliva may affect it, unlike a large amount of water, which is not affected.
The questioner:
Is using soap instead of earth sufficient for purifying a dog's saliva?
The Shaykh:
The default is earth, if it is available, based on the text of the Messenger of Allah (peace and blessings be upon him), and that is what is preferred. If earth is not available, then soap and the like are sufficient. However, if earth is available, one should do what the Prophet (peace and blessings be upon him) commanded, and it is better to use it first. Yes.
