Tahajjud is a voluntary night prayer, offered after sleeping and before Fajr. It isn't obligatory, but it's one of the most highly recommended and rewarded acts of worship outside the five daily prayers.

وَمِنَ ٱلَّيْلِ فَتَهَجَّدْ بِهِۦ نَافِلَةً لَّكَ عَسَىٰٓ أَن يَبْعَثَكَ رَبُّكَ مَقَامًا مَّحْمُودًا

"And from the night, pray Tahajjud as an additional prayer for you; it is expected that your Lord will raise you to a praised station."

Qur'an 17:79

When is Tahajjud prayed?

Tahajjud falls any time after Isha and before Fajr, once you've slept — even briefly. The night is traditionally divided into three parts, and the final third carries the greatest virtue:

  • First third: from Isha until roughly a third of the way to Fajr
  • Middle third: the central portion of the night
  • Last third: from roughly two-thirds through the night until Fajr begins — the most virtuous time to pray

Because night length changes with the seasons, the last third isn't a fixed clock time — it shifts throughout the year. A prayer app that calculates it from your actual sunset and Fajr times (rather than a flat guess like "3 AM") will be far more accurate.

Why the last third of the night?

The Prophet Muhammad ﷺ said that Allah descends to the lowest heaven during the last third of every night, saying: "Who is calling upon Me, that I may answer him? Who is asking of Me, that I may give him? Who is seeking My forgiveness, that I may forgive him?" (Sahih al-Bukhari & Sahih Muslim). This is one of the reasons scholars describe the last third of the night as an especially accepted time for dua.

How to pray Tahajjud

  1. Make the intention (niyyah) to pray Tahajjud.
  2. Pray in pairs of two rak'ahs (like other voluntary prayers), reciting normally.
  3. Pray as many pairs as feels comfortable — the Prophet ﷺ prayed anywhere from a few rak'ahs to eleven, depending on the night.
  4. Take your time. Tahajjud is typically prayed more slowly and reflectively than obligatory prayers.
  5. Finish with Witr if you haven't already prayed it earlier in the night.

There's no minimum — even two rak'ahs counts, and consistency matters more than length.

Tips for actually waking up

  • Sleep a little earlier than usual so waking before Fajr doesn't mean cutting sleep too short.
  • Set an alarm for a set time before your local Fajr, rather than guessing.
  • Start small — even one night a week, two rak'ahs, builds the habit.
  • Keep water nearby to help you wake up properly before starting.
