"The Messenger of Allah ﷺ moved until he came to Al-Muzdalifah, where he prayed Maghrib and 'Isha' with one Adhan and two Iqamahs, and he did not offer any prayer in between them." (Using translation from Nasāʾī 656)  

دَفَعَ رَسُولُ اللهِ ﷺ «حَتَّى انْتَهَى إِلَى الْمُزْدَلِفَةِ فَصَلَّى بِهَا الْمَغْرِبَ وَالْعِشَاءَ بِأَذَانٍ وَإِقَامَتَيْنِ لَمْ يُصَلِّ بَيْنَهُمَا شَيْئًا»  

"We were with him (Ibn 'Umar) in Jam' (Muzdalifah), and he called the Adhan, then the Iqamah, then he led us in praying Maghrib. Then he said: 'The prayer,' and he led us in praying 'Isha', two Rak'ahs. I said: 'What is this prayer?' He said: 'This is how I prayed with the Messenger of Allah ﷺ in this place.'" (Using translation from Nasāʾī 657)  

كُنَّا مَعَهُ بِجَمْعٍ فَأَذَّنَ ثُمَّ أَقَامَ وَصَلَّى بِنَا الْمَغْرِبَ ثُمَّ قَالَ «الصَّلَاةَ» فَصَلَّى بِنَا الْعِشَاءَ رَكْعَتَيْنِ فَقُلْتُ مَا هَذِهِ الصَّلَاةُ؟ قَالَ «هَكَذَا صَلَّيْتُ مَعَ النَّبِيِّ ﷺ فِي هَذَا الْمَكَانِ»
