Equating the pig with the dog in washing away impurity seven times

Question:
Honorable Shaykh, may Allah grant you success! It is known that acts of worship are based on specific texts, so why is the impurity of the pig washed seven times, one of which with earth, like the dog, given that it is not established that the Messenger of Allah (peace and blessings be upon him) equated the dog and the pig?

Answer:
This is the chapter on qiyas (analogical reasoning), specifically qiyas al-awla (argument from stronger evidence), which they call qiyas al-jali (obvious analogy). There is no disagreement among scholars on this. If the dog is washed seven times, then the pig is even more so. From the saying of Allah the Exalted, "So do not say to Him 'What is it?'", they said this indicates that striking is forbidden from an even stronger perspective. This is called qiyas al-jali, and there is no disagreement among the people of knowledge, even the Zahiris say yes.
