Is the mother's husband called an "uncle"?

Question:
Is the mother's husband called an "uncle"?

Answer:
Based on the apparent meaning of what al-Hafiz said, which is the well-known view among us, but there is no evidence for it. When al-Hafiz said this, it was as if he had found it in something, or perhaps it was his uncle, because it is the custom of the Arabs to call the son of an elder uncle, as Abu Talhah was the son of Anas's uncle...
The point is that the son of an uncle is called an uncle by the Arabs, and the elder is called an uncle. Even if the elder is the son of an uncle, they call him uncle, as Mu'adh and Ma'udh said to 'Abd al-Rahman ibn 'Awf: "O uncle, where is Abu Jahl?" And 'Abd al-Rahman ibn 'Awf was not from the Ansar, but was a Qurayshi emigrant. They called him "O uncle" because he was older in age and they were young. So they have a rule that the young person says to the elder "O uncle" or "O father," and this is still the case today.
