When Does Tahajjud End?
The short answer: Tahajjud ends the moment Fajr begins. Not at sunrise, not at the Fajr adhan's end — at the start of Fajr time. Here is tonight's deadline for your city:
Tonight's end time
Times are calculated for planning. If your local mosque or a trusted local timetable gives a different time, follow your local mosque.
The deadline, explained
Tahajjud belongs to the night, and the Islamic night runs from Maghrib to Fajr. When true dawn breaks and Fajr time enters, the night — and the Tahajjud window with it — is over. This is why our tahajjud calculator treats Fajr as a hard deadline on every result it shows: "Tahajjud ends at Fajr." Sunrise is a different boundary entirely; it ends the time for praying Fajr itself. A calculator that runs the night to sunrise has drawn the line in the wrong place.
What happens if Fajr begins while you are praying?
It happens to everyone who prays at night eventually. The mainstream guidance, stated gently: finish the prayer you are in calmly — do not rush it into something careless — and let that prayer's intention stand as you made it. Scholars discuss the details of completing a voluntary prayer once the dawn has entered, and their discussions differ; for the precise ruling you act on, ask a scholar or teacher you trust locally. What is not in dispute is the shape of the lesson: the deadline is real, and it rewards planning rather than panic.
Suhoor and the deadline in Ramadan
In Ramadan the same moment closes two doors at once. Suhoor — the pre-dawn meal — ends at Fajr, and so does Tahajjud. One deadline, two acts of worship racing toward it. The practical pattern most people land on: eat Suhoor first while there is still comfortable time, then pray in what remains of the last third, so neither is rushed. Our Tahajjud in Ramadan guide works through the pacing of a whole month of nights.
Leaving yourself enough time
The fix for deadline anxiety is arithmetic, not willpower: plan backwards. Decide how long you want to pray, add your freshen-up minutes, and subtract both from Fajr. That is exactly what the Tahajjud wake-up planner does for your city, tonight — it shows your alarm time alongside the start of the last third, so you can see your margin at a glance. A small margin kept every night beats a heroic margin kept once.
Frequently asked questions
Does Tahajjud end at Fajr or at sunrise?
At Fajr. The night — and with it the time for Tahajjud — ends when true dawn breaks and the Fajr prayer time enters, not at sunrise. Sunrise ends the Fajr prayer's own time, which is a different deadline. Any calculator that runs the night to sunrise is using the wrong boundary.
What if I wake up ten minutes before Fajr?
Pray. Two quick rak'ahs and a short dua inside the last third are worth more than a perfect plan that never happens. If time is very tight, pray a shortened prayer and make your most important dua. Witr, if not yet prayed, can be a single rak'ah.
Can I pray Tahajjud after the Fajr adhan?
Once Fajr time has begun, the Tahajjud window has closed — the night prayer belongs to the night. What you pray after that is Fajr itself (its sunnah and fard). If this happens often, move your alarm earlier in small steps; our wake-up planner works backwards from Fajr for exactly this.
