«الْمَقْلُوبُ»
Maqlūb is a report in which an established order or attribution has been reversed, whether in a transmitter's name or in the matn.
It does not mean every report with an alternative formulation. The critic must show that a reliably preserved sequence was A–B while a particular route presents B–A. If a person is genuinely known by two names, that alone does not constitute reversal.
In the isnād: a transmitter's name and his father's name are reversed, or a recognized relationship is transposed.
In the matn: two words or semantic relations exchange positions and alter the original meaning. The following example concerns the right and left hands.
