حَدَّثَنِي أَبُو غَسَّانَ الْمِسْمَعِيُّ مَالِكُ بْنُ عَبْدِ الْوَاحِدِ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ قَالَ أَبُو غَسَّانَ حَدَّثَنَا مُعَاذٌ وَقَالَ إِسْحَاقُ أَخْبَرَنَا مُعَاذُ بْنُ هِشَامٍ صَاحِبِ الدَّسْتَوَائِيِّ و حَدَّثَنِي أَبِي عَنْ عَامِرٍ الْأَحْوَلِ عَنْ مَكْحُولٍ عَنْ عَبْدِ اللَّهِ بْنِ مُحَيْرِيزٍ عَنْ أَبِي مَحْذُورَةَ أَنَّ نَبِيَّ اللَّهِ عَلَّمَهُ هَذَا الْأَذَانَ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ ثُمَّ يَعُودُ فَيَقُولُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ حَيَّ عَلَى الصَّلَاةِ مَرَّتَيْنِ حَيَّ عَلَى الْفَلَاحِ مَرَّتَيْنِ. زَادَ إِسْحَاقُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ لَا إِلَهَ إِلَّا اللَّهُ

It was narrated from Abu Mahdhurah that the Prophet of Allah (s.a.w) taught him this Adhan: "Allahu akbaru Allahu akbar; Ashhadu an la ilaha illallah, Ashhadu an la ilaha illallah; Ashhadu anna Muhammadan Rasul Allah, Ashhadu anna Muhammadan Rasul Allah (Allah is Most Great, Allah is Most Great; I bear witness that none has the right to be worshiped but Allah, I bear witness that none has the right to be worshiped but Allah; I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah)." Then he should go back and say: "Ashhadu an la ilaha illallah (I bear witness that none has the right to be worshiped but Allah)," twice; ''Ashhadu anna Muhammadan Rasul Allah (I bear witness that Muhammad is the Messenger of Allah)," twice; "Hayya 'alas-salat (Come to prayer)," twice; "Hayya 'alal-falah (Come to prosperity)," twice. (One of the narrators) Ishaq added: "Allahu akbaru Allahu akbar; La ilaha illallah (Allah is Most Great, Allah is Most Great; none has the right to be worshiped but Allah)."
