Tahajjud

Tahajjud is among the addad words — applied to both sleep and night prayer; the mutahajjid is one who rises to prayer from sleep, casting slumber off. 'A'isha, Ibn 'Abbas and Mujahid glossed "nashi'at al-layl" as rising to pray after sleep. ²

Voluntary night prayer after sleep; Ibn al-'Arabi records three views — sleep then prayer then sleep then prayer, prayer after sleep, or whatever follows 'isha' — the Malikis prefer the second. ^{2 3}

Qiyam al-layl properly denotes occupying the night with prayer alone, though it extends to any devotion such as recitation and tasbih; so qiyam is broader than tahajjud. ³
