Tahajjud vs Qiyam al-Layl
Two terms, one night, endless confusion. The short version: Qiyam al-Layl is the umbrella; Tahajjud is the prayer under it. Here is the difference scholars actually draw, and why the distinction matters less than the worship. When you are ready to time either one, the tahajjud calculator marks the window both live in.
Qiyam al-Layl: the umbrella
Qiyam al-layl means "standing the night" — any worship that fills part of the night: prayer, reciting Quran, dhikr, dua, seeking forgiveness. It has no requirement of sleep before it and no fixed form. Pray after Isha, read Quran at 2 AM, sit in remembrance before Fajr: all of it is Qiyam al-Layl. Taraweeh in Ramadan is Qiyam al-Layl with a seasonal name and a congregation.
Tahajjud: the prayer, classically after sleep
Tahajjud comes from a root tied to leaving sleep — and in the classical definitions it names the prayer of the night, most precisely the prayer a person rises to after having slept. The Quran uses the word's root in the command to the Prophet ﷺ (17:79), and the Prophet's ﷺ own habit — sleep, then rise in the last third — fixed the picture the word carries. Where Qiyam is the whole night-shift of worship, Tahajjud is its centrepiece: rak'ahs prayed in the dark, above all in the last third.
How the terms overlap in everyday use
In ordinary speech — and in many articles and FAQ pages, including some that rank for these searches — the two words are used almost interchangeably, and "Tahajjud" often just means "the night prayer whenever you pray it." We are more precise on this site, because precision here costs nothing: night worship of every kind is Qiyam al-Layl; the prayer itself, classically after sleep, is Tahajjud. If your local teacher uses the words loosely, nothing is lost — the acts are the same, and Allah rewards the worship, not the vocabulary.
Why the difference still helps
It answers real questions cleanly. "I prayed after Isha without sleeping — did I pray Tahajjud?" Under the precise terms: you prayed Qiyam al-Layl in full, and (on the stricter naming) Tahajjud's specific name belongs to the after-sleep prayer — a discussion our dedicated guide treats in full, with both scholarly views. "Is my Taraweeh enough Qiyam?" Yes — and rising later adds Tahajjud to the same night. And when the hadith promises response in "the last third," it is speaking of the time, whichever of these acts fills it.

Frequently asked questions
Is Tahajjud a type of Qiyam al-Layl?
Yes. Qiyam al-Layl is the wide category — standing the night in any worship: prayer, Quran, dhikr, dua. Tahajjud is the prayer within it, classically the prayer prayed after sleeping part of the night. Every Tahajjud is Qiyam al-Layl; not every hour of Qiyam al-Layl is Tahajjud prayer.
Which word does the Quran use?
The Quran uses the root of Tahajjud once — "keep vigil in it" (17:79), addressed to the Prophet ﷺ — and speaks of the night standing (qiyam) and the night vigil more broadly, including the long passage opening Surah Al-Muzzammil (73). Scholars built the everyday vocabulary from both.
If I pray after Isha without sleeping, what is it called?
On the stricter naming, it is Qiyam al-Layl — night prayer in full standing and reward — while 'Tahajjud' is reserved for prayer after sleep. On the broader usage many scholars allow, it is Tahajjud too. The worship is identical either way; our guide on praying without sleeping lays out both views fairly.
Is Taraweeh Tahajjud or Qiyam?
Taraweeh is the name for Qiyam al-Layl in Ramadan, prayed in congregation after Isha. It belongs to the same night-standing family; a worshipper who also rises in the last third is adding Tahajjud in its classic after-sleep form to the same night.
