The Messenger of Allah ﷺ used to attack the enemy when it was dawn. He would listen to the Adhan; so if he heard an Adhan, he stopped, otherwise made an attack. Once on hearing a man say: Allah is the Greatest, Allah is the Greatest, the Messenger of Allah ﷺ remarked: He is following al-Fitra (al-Islam). Then hearing him say: I testify that there is no god but Allah. there is no god but Allah, the Messenger of Allah ﷺ said: You have come out of the Fire (of Hell). They looked at him and found that he was a goat herd.  

كَانَ رَسُولُ اللَّهِ ﷺ يُغِيرُ إِذَا طَلَعَ الْفَجْرُ وَكَانَ يَسْتَمِعُ الأَذَانَ فَإِنْ سَمِعَ أَذَانًا أَمْسَكَ وَإِلاَّ أَغَارَ فَسَمِعَ رَجُلاً يَقُولُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ فَقَالَ رَسُولُ اللَّهِ ﷺ عَلَى الْفِطْرَةِ ثُمَّ قَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ فَقَالَ رَسُولُ اللَّهِ ﷺ خَرَجْتَ مِنَ النَّارِ فَنَظَرُوا فَإِذَا هُوَ رَاعِي مِعْزًى  

That the Prophet ﷺ would not attack except near the time of Fajr, so if he heard the Adhan he would refrain, and if not, then he would attack. So he listened one day and heard a man saying: "Allahu Akbar, Allahu Akbar," so he said: "Upon the Fitrah." Then he said: "I bear witness that none has the right to be worshipped but Allah." So he said: "You have departed from the Fire."  

كَانَ النَّبِيُّ ﷺ لاَ يُغِيرُ إِلاَّ عِنْدَ صَلاَةِ الْفَجْرِ فَإِنْ سَمِعَ أَذَانًا أَمْسَكَ وَإِلاَّ أَغَارَ فَاسْتَمَعَ ذَاتَ يَوْمٍ فَسَمِعَ رَجُلاً يَقُولُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ فَقَالَ عَلَى الْفِطْرَةِ فَقَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ فَقَالَ خَرَجْتَ مِنَ النَّارِ  

[Machine] While we were with the Messenger of Allah ﷺ on a journey, we heard a man saying "Allahu Akbar, Allahu Akbar." The Prophet ﷺ said, "On the Fitrah (natural disposition)." Then he said, "I bear witness that there is no god but Allah and I bear witness that Muhammad is the Messenger of Allah." The Prophet ﷺ said, "This man has come out of the Fire."  

بَيْنَمَا نَحْنُ مَعَ رَسُولِ اللهِ ﷺ فِي سَفَرٍ إِذْ سَمِعَ رَجُلًا يَقُولُ اللهُ أَكْبَرُ اللهُ أَكْبَرُ فَقَالَ النَّبِيُّ ﷺ عَلَى الْفِطْرَةِ فقَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللهِ فَقَالَ النَّبِيُّ ﷺ خَرَجَ هَذَا مِنَ النَّارِ

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُغِيرُ عِنْدَ صَلَاةِ الْفَجْرِ فَيَسْتَمِعُ الْأَذَانَ فَإِذَا سَمِعَ الْأَذَانَ أَمْسَكَ وَإِلَّا أَغَارَ فَاسْتَمَعَ ذَاتَ يَوْمٍ فَسَمِعَ رَجُلًا يَقُولُ اللهُ أَكْبَرُ اللهُ أَكْبَرُ فَقَالَ رَسُولُ اللهِ ﷺ عَلَى الْفِطْرَةِ فَقَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ فَقَالَ خَرَجْتَ مِنَ النَّارِ

[Machine] The translation of the passage is as follows: "The Messenger of Allah ﷺ used to repeat the words of the Mu'adhdhin when he heard him saying, 'Allah is the Greatest, Allah is the Greatest.'

And when the Mu'adhdhin said, 'I bear witness that Muhammad is the Messenger of Allah,' he would say the same words."  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا سَمِعَ الْمُؤَذِّنَ يَقُولُ اللهُ أَكْبَرُ اللهُ أَكْبَرُ قَالَ مِثْلَ قَوْلِهِ وَإِذَا قَالَأَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ قَالَ مِثْلَ قَوْلِهِ وَإِذَا قَالَ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللهِ قَالَ مِثْلَ قَوْلِهِ

بَيْنَمَا رَسُولُ اللهِ ﷺ فِي بَعْضِ أَسْفَارِهِ إِذْ سَمِعَ مُنَادِيًا يَقُولُ اللهُ أَكْبَرُ اللهُ أَكْبَرُ فَقَالَ رَسُولُ اللهِ ﷺ «عَلَى الْفِطْرَةِ» فَقَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ فَقَالَ رَسُولُ اللهِ ﷺ «خَرَجَ مِنَ النَّارِ»  

"سَمِعَ النبِيُّ ﷺ رَجُلًا وَهُوَ فِى مَسِيرٍ لَهُ يَقُولُ: أكْبَرُ الله أكْبَرُ الله. فَقَالَ: عَلَى الفِطرَةِ، فَقَالَ: اشْهَدُ أنْ لاَ إِلَهَ إِلَّا الله فَقَالَ: خَرَجَ مِنَ النَّارِ، فَاسْتَبَقَ القَوْمُ إِلَى الرَّجُلِ فإِذَا رَاعِى غَنَمٍ حَضَرَتِ الصَّلاَةُ فَقَامَ يُؤَذنُ ".
