In plain terms
Mani'

Source entry · Editorial review pending ↗
Mani' names something that blocks a ruling from applying, even when every other requirement for it has already been met.
What it means for me: Mani' explains why a ruling you expected does not apply to you. Every other requirement can be satisfied, and this one thing still stands in the way. You cannot reason your way around it by satisfying more of the other requirements.
Example: Two relatives meet every condition for a share of an estate. One caused the death of the person they would inherit from, and that blocks the share regardless. It is a standard example of mani' at work.
Do not confuse with: Shart, condition. A missing shart means a requirement was never met. A mani' is different: every requirement is met, and something else still overrides it.
If scholars differ: Legal theorists agree mani' belongs among the situational rulings, alongside sabab and shart. They differ on classifying specific circumstances as a genuine impediment rather than simply an unmet condition.
