"When Al-Ḥassan did what he did with Mu`āwiyah..." instead of, "When Al-Ḥusayn did what he did..."
Two of the three manuscripts that the editor had were in agreement.
All three were written in the 11th century and there is no correct justification for choosing a conflicting wording when two manuscripts agree against it.
If we were to assume that this occurred due to some sort of copyist error, it would be far likelier for us to assume that the words "with Mu`āwiyah" were dropped accidentally, instead of assuming that "with Mu`āwiyah" was added... twice!
No, this could not have been a mere slip of the pen.
The text is awkwardly worded and a more appropriate wording would be:
When Al-Ḥusayn did what he did, Allah the most majestic made upon himself to not place the wasiyyah and Imamate anywhere but within [HIS progeny] (peace be onto him).
Naturally, when a commercial print is released, footnotes will be removed after all.
