Sunan an-Nasa'i #533 · The Book of the Times (of Prayer)

Sunan an-Nasa'iIt was narrated that Jabir bin Samurah said
Sunan an-Nasa'i · Book 6 · The Book of the Times (of Prayer)
Sunan an-Nasa'i · كتاب 6 · كتاب مواقيت الصلاة
"The Messenger of Allah (ﷺ) used to delay the later 'Isha'."[1] [1] It is described as the later 'Isha' prayer because the Maghrib prayer is sometimes called 'Isha' prayer, but it is the first 'Isha'. Some scholars are of the opinion that it is disliked to call Maghrib 'Isha' without qualifying it as the first 'Isha'. See Fath Al-Bari
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سِمَاكٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُؤَخِّرُ الْعِشَاءَ الآخِرَةَ ‏.‏
