Sahih Muslim, 3111

Ubaidullah b. 'Abdullah b. 'Umar reported on the authority of his father (Allah be pleased with them) that Allah's Messenger (ﷺ) combined the sunset and 'Isha', prayers at Muzdalifa and there was no prostration (i. e. any rak'ahs of Sunan or Nawafil prayers) in between them. He observed three rak'ahs of the sunset prayer and two rak'ahs of the 'Isha' prayer, and 'Abdullah (b. 'Umar) observed the prayers in this very manner (at Muzdalifa) until he met his Lord

Rapporté par Ubaidullah b. ‘Abdullah b. ‘Umar d’après son père رضي الله عنهما : Le Messager d’Allah ﷺ a réuni les prières du coucher du soleil et de ‘Isha à Muzdalifa, sans prosternation (c’est-à-dire sans rak‘a Sunna ou Nawafil) entre les deux. Il a accompli trois rak‘a pour la prière du coucher du soleil et deux rak‘a pour la prière de ‘Isha, et ‘Abdullah b. ‘Umar a continué à prier de cette façon à Muzdalifa jusqu’à sa mort
