حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا الْحَارِثُ بْنُ عُبَيْدٍ، عَنْ مُحَمَّدِ بْنِ عَبْدِ الْمَلِكِ بْنِ أَبِي مَحْذُورَةَ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ عَلِّمْنِي سُنَّةَ الأَذَانِ ‏.‏ قَالَ فَمَسَحَ مُقَدَّمَ رَأْسِي وَقَالَ ‏"‏ تَقُولُاللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ تَرْفَعُ بِهَا صَوْتَكَ ثُمَّ تَقُولُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ تَخْفِضُ بِهَا صَوْتَكَ ثُمَّ تَرْفَعُ صَوْتَكَ بِالشَّهَادَةِ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ حَىَّ عَلَى الصَّلاَةِ حَىَّ عَلَى الصَّلاَةِ حَىَّ عَلَى الْفَلاَحِ حَىَّ عَلَى الْفَلاَحِ فَإِنْ كَانَ صَلاَةَ الصُّبْحِ قُلْتَ الصَّلاَةُ خَيْرٌ مِنَ النَّوْمِ الصَّلاَةُ خَيْرٌ مِنَ النَّوْمِ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ لاَ إِلَهَ إِلاَّ اللَّهُ ‏"‏ ‏.‏
Translation
Abu Mahdhurah reported; I said; Messenger of Allah, teach me the method of ADHAN (how to pronounce the call to prayer). He wiped my forehead (with his hand) and asked me to pronounce; Allah is most great. Allah is most great. Allah is most great. Allah is most great, raising your voice while saying them (these words). Then you must raise your voice in making the testimony

I said: O Messenger of Allah, teach me the practice of the call to prayer. He said: He passed his hand over the front of my head and said: You say, 'Allahu Akbar, Allahu Akbar, Allahu Akbar, Allahu Akbar,' raising your voice with it. Then you say, 'Ashhadu an la ilaha illa Allah, Ashhadu an la ilaha illa Allah, Ashhadu anna Muhammadan Rasul Allah, Ashhadu anna Muhammadan Rasul Allah,' lowering your voice with it. Then you raise your voice with the testimony, 'Ashhadu an la ilaha illa Allah, Ashhadu an la ilaha illa Allah, Ashhadu anna Muhammadan Rasul Allah, Ashhadu anna Muhammadan Rasul Allah, Hayya 'ala al-salah, Hayya 'ala al-salah, Hayya 'ala al-falah, Hayya 'ala al-falah.' If it is the morning prayer, you say, 'Al-salatu khayrun min al-nawm, Al-salatu khayrun min al-nawm, Allahu Akbar, Allahu Akbar, la ilaha illa Allah.'
