"I saw Sa'eed bin Jubari in Jam'.[1] He stood and prayed Maghrib, three Rak'ahs, then he stood and prayed 'Isha', two Rak'ahs. Then he mentioned that Ibn 'Umar had done the same thing in that place, and he mentioned that the Messenger of Allah ﷺ has done the same thing in that place. [1] Meaning Al-Muzdalifah. (Using translation from Nasāʾī 481)   

أَنَّ النَّبِيَّ ﷺ صَنَعَ مِثْلَ ذَلِكَ  

It was narrated from Ibn 'Umar that he prayed in Jam'a with the Messenger of Allah ﷺ with one Iqamah. (Using translation from Nasāʾī 659)  

أَنَّهُ «صَلَّى مَعَ رَسُولِ اللهِ ﷺ بِجَمْعٍ بِإِقَامَةٍ وَاحِدَةٍ»  

It was narrated from Salim, from his father, that the Prophet ﷺ joined them (Maghrib and 'Isha') in Al-Muzdalifah, and he prayed each of them with an Iqamah, and he did not offer any voluntary prayer before or after either of them. (Using translation from Nasāʾī 660)  

أَنَّ رَسُولَ اللهِ ﷺ «جَمَعَ بَيْنَهُمَا بِالْمُزْدَلِفَةِ صَلَّى كُلَّ وَاحِدَةٍ مِنْهُمَا بِإِقَامَةٍ وَلَمْ يَتَطَوَّعْ قَبْلَ وَاحِدَةٍ مِنْهُمَا وَلَا بَعْدَهَا»
