Hanafi
Triggered by forgetfully omitting or delaying a wajib act. Method: in the final sitting after tashahhud, give one salam to the right, make two prostrations, sit, repeat the tashahhud and closing prayers, then finish with both salams.

Fixing prayer mistakes
Mid-prayer, somewhere in the third rak'ah (or was it the second?), comes the cold spike of did I already sit? Here is the thing the panic doesn't know: the prayer was designed by the Merciful for people who lose count. There's a built-in repair (two extra prostrations), plus explicit rules for doubt, sleep, travel, planes, and the years someone didn't pray at all. Nothing on this page is an emergency.
Sujud as-sahw: the forgetfulness prostration, by school
Two prostrations repair forgetful slips; all four schools agree on that. Where they differ is placement and trigger. Find your school (or your mosque's), learn one method, ignore the other three columns forever.
Maliki
The clean split: for an omission, prostrate twice before salam; for an addition, prostrate twice after salam (then repeat tashahhud and salam). If both happened, before-salam takes priority. A missed pillar isn't patched by prostration; the rak'ah itself gets fixed first.
Shafi'i
Two prostrations before the closing salam, after the final tashahhud, whatever the cause: addition, omission of an emphasized part like the first tashahhud, or unresolved doubt. The prostrations are recommended; forgetting even them doesn't invalidate the prayer.
Hanbali
Generally before salam, with stated exceptions after salam (e.g., when salam was given early by mistake). Ibn 'Uthaymin's well-known case-based scheme (addition → after; omission → before; doubt resolved by likelihood → after) is his detailed application: cited widely, but attribute it to him, not to 'the Hanbali school' flatly.
Mistake questions, answered
I just realized I made a mistake mid-prayer. What do I do right now?
Keep praying, that's the rule that rescues everything. Almost no slip requires restarting: an added action, a missed sitting, a wrong recitation are repaired by the forgetfulness prostration (sujud as-sahw) at the end, two extra prostrations whose exact placement differs by school. The instinct to scrap the prayer and start over is almost always the wrong move, and doing it habitually trains exactly the anxiety this system exists to prevent.
I can't remember if I prayed three rak'ahs or four.
The shared rule: build on what you're certain of. If genuinely unsure between three and four, treat it as three, complete the prayer, and make the forgetfulness prostration. The Hanafi school (and Ibn 'Uthaymin among later Hanbalis) adds: if one side genuinely feels more likely, you may follow that stronger inclination. What no school asks: replaying the prayer in your head like game film. One honest judgment, then done.
I doubt my prayers constantly. Every day. Multiple times.
Then the doubt rules above stop applying to you, deliberately. Every school's scholars say the same thing about constant, intrusive, can't-let-go doubt: ignore it, presume the prayer valid, do not repeat. This is waswas, and feeding it with repetition makes it grow; the tradition's own prescription is to starve it. If checking and redoing has crept into wudu, ghusl, and food too, please treat it as the recognized condition it is, religious OCD responds to treatment, and a scholar plus an OCD-informed clinician is the sunnah-compatible team. You are not weak in faith; you have an anxiety pattern with a fiqh-approved off-ramp.
I slept through Fajr. Is it over?
No, this is the gentlest rule in the system, straight from the hadith: whoever sleeps through or forgets a prayer prays it when they wake or remember, and that is its time. No penalty, no compounding guilt clause. Set the alarms, structure the sleep, and when biology wins anyway, pray on waking and move on with your day.
I skipped prayers on purpose, years of them. What now?
First: the door back is fully open, and today's five matter more than the backlog. On the backlog itself there are two real positions: the majority across the four schools, repent and make up the missed prayers, estimating the count reasonably and chipping away sustainably (one qada with each daily prayer is a common pattern); and the view associated with Ibn Taymiyyah, deliberately abandoned prayers can't be made up, so repent sincerely and multiply voluntary prayer instead. Both agree on repentance and on never despairing. Pick your path with a scholar you trust, and be wary of any approach that turns return-to-prayer into a decade of self-punishment, sustainability is the fiqh.
Do converts make up the prayers from before Islam?
No. Becoming Muslim wipes the slate, prayers, fasts, all of it. Your obligations start at your shahada. If you wobbled in your first months after converting, those months fall under the ordinary missed-prayer discussion above, but the pre-Islam years are simply not on the books.
How does prayer work when I travel?
Past roughly 48-55 miles (the schools' stated figures cluster around 77-89 km, each with its own conversion, don't let anyone sell you one exact number), the four-rak'ah prayers (Dhuhr, Asr, Isha) shorten to two, starting once you've left your city's built-up area. How long it lasts at the destination differs: intending to stay 15+ days ends traveler status for Hanafis, about four days for the other schools (with different counting details). Combining Dhuhr-Asr or Maghrib-Isha while traveling is allowed in the Maliki, Shafi'i, and Hanbali schools; the Hanafi school instead prays the first at the end of its window and the second at the start of its own, same practical relief, different mechanism.
How do I pray on a plane?
If the prayer's window will fully pass before landing, pray on the plane rather than skip, that part is agreed. Do it as fully as conditions allow: standing with normal bowing and prostration if there's space (galley areas, when crew permits), seated with gestures only as the genuine last resort. The school detail: Hanafi answers require a gestures-only seat prayer to be repeated after landing, and some Shafi'i answers require repeating in-flight obligatory prayers generally once settled. Two planning moves beat most dilemmas: check whether the flight even spans a full window, and use the combining/qasr rules your school gives travelers. Never unbuckle against crew instructions for prayer, the deen does not require a turbulence injury.
The school positions above are compressed from their institutions' published answers. Categories like "pillar" and "wajib" carry school-specific meanings, so for anything beyond the common cases (a missed pillar, mistakes behind an imam, a mistake inside the forgetfulness prostration itself), get the answer from your own school's scholar rather than a cross-school average. And the waswas rule is not a footnote: if doubt is a daily visitor, the ruling for you is to ignore it.
