The Adhan For One Who Is Combining Two Prayers After The Time Of The First Prayer Has Gone
Sunan an-Nasai
أَخْبَرَنِي إِبْرَاهِيمُ بْنُ هَارُونَ، قَالَ حَدَّثَنَا حَاتِمُ بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا جَعْفَرُ بْنُ مُحَمَّدٍ، عَنْ أَبِيهِ، أَنَّ جَابِرَ بْنَ عَبْدِ اللَّهِ، قَالَ دَفَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم حَتَّى انْتَهَى إِلَى الْمُزْدَلِفَةِ فَصَلَّى بِهَا الْمَغْرِبَ وَالْعِشَاءَ بِأَذَانٍ وَإِقَامَتَيْنِ وَلَمْ يُصَلِّ بَيْنَهُمَا شَيْئًا .
It was narrated that Jabir bin 'Abdullah said: "The Messenger of Allah (S.A.W) 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."
