كتاب الأذان
Read the English translation first, with the original Arabic directly underneath.
It was narrated from Sa'eed bin Jubair that he prayed Maghrib and 'Isha' in Jam' (Muzdalifah) with one Iqamah, then he narrated that Ibn 'Umar had done that, and Ibn 'Umar narrated that the Prophet (ﷺ) had done that.
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، وَسَلَمَةِ بْنِ كُهَيْلٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، أَنَّهُ صَلَّى الْمَغْرِبَ وَالْعِشَاءَ بِجَمْعٍ بِإِقَامَةٍ وَاحِدَةٍ ثُمَّ حَدَّثَ عَنِ ابْنِ عُمَرَ أَنَّهُ صَنَعَ مِثْلَ ذَلِكَ وَحَدَّثَ ابْنُ عُمَرَ أَنَّ النَّبِيَّ صلى الله عليه وسلم صَنَعَ مِثْلَ ذَلِكَ .
