1Anger and doubt cannot really occupy the same moment. Anger sharpens everything to a point, and a genuine maybe blunts it.
This is why an honest question does more than an argument. Not a challenge, which hardens things, but a real one: what if I have got part of this wrong. If you can hold that for a second and actually mean it, you will usually feel the heat drop a little, because the certainty propping it up has gone soft.
Islamic evidence
His arrogance leads him to sin (Quran 2:206). The verse traces a sequence anyone in a row will recognise: a person is corrected, the pride will not take it, and the pride carries them onward.
“When he is told, ‘Beware of God,’ his arrogance leads him to sin. Hell is enough for him: a dreadful resting place”
Qur'an 2:206
Psychological evidence
In a brain imaging experiment, people who were insulted and then prompted to dwell on it showed activity in a region of the cingulate cortex that tracked both their reported anger and how aggressive they generally were. That supports anger being an actively maintained state rather than a passing spark, and something maintained can be interrupted. Whether deliberately introducing doubt is what interrupts it has not been tested this way.

Why it works. Anger needs to be sure, so anything that makes you genuinely unsure takes some of its fuel away.

none yet2Not understanding what is happening frightens a person before it angers them. If you flare up when a situation is unclear, you are meeting something very old in yourself rather than a fault you invented.
Watch the order of it next time. First the blank, the not knowing what this means or where it is going, then a tightening in the chest or jaw, then the sharp words. Naming the fear underneath does not make the situation any clearer, but it stops you treating your own heat as proof that someone has wronged you.
Islamic evidence
Do not follow blindly what you do not know to be true: ears, eyes, and heart, you will be questioned about all these (Quran 17:36). Fear fills a gap with a guess, and this is a gentle instruction not to act on the guess as though you already knew.
“Do not follow blindly what you do not know to be true: ears, eyes, and heart, you will be questioned about all these”
Qur'an 17:36
Psychological evidence
A review of anger from a cognitive neuroscience angle describes reactive aggression as coming out of a basic threat system in the brain, involving the amygdala, hypothalamus and periaqueductal gray, rather than being a strategy a person selects. It is a review of existing work, not a single decisive study, so take it as a way of organising the picture rather than a measurement of you. What it does support is the ordinary experience that the reaction lands before the thinking does.

Review detail
Why it works. Fear is a faster and older reaction than working things out, so anger in an unclear moment is often that fear arriving first.
When not to. If the not knowing brings a fear that will not settle at all, or old danger comes back with it, that is worth taking to someone trained rather than sitting with alone.

none yet3The aim is not to work out the answer. It is to keep moving while the answer is missing, and to find that the fear does not have to run the day.
When something is unsettled, your mind hands you one job after another: replay it, check it, decide what they really meant. You can put those down and still get through the afternoon. Set the bar there for now, at carrying on without the matter being closed, and notice afterwards that the not knowing did you no harm.
Islamic evidence
Everything to do with this affair is in God's hands (Quran 3:154). You are allowed to stop needing the full picture, because holding all of it was never your work.
“After sorrow, He caused calm to descend upon you, a sleep that overtook some of you. Another group, caring only for themselves, entertained false thoughts about God, thoughts more appropriate to pagan ignorance, and said, ‘Do we get a say in any of this?’…”
Qur'an 3:154
Psychological evidence
Across four experiments, being provoked led to more aggressive behaviour, and part of how it did so was by feeding angry rumination and draining self-control. These were laboratory provocations with volunteers, so the effects are modest and the setting is artificial. Still, the useful part holds: going back over it is not a neutral act, it is one of the things keeping the anger within reach, so declining to solve it is doing something rather than giving up.

Why it works. Chasing certainty keeps the whole scene switched on in your head, and leaving it open lets your body come down on its own.
When not to. If what is unresolved concerns your safety or someone else's, that one needs answering rather than tolerating.
