Anas b. Malik reported:
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ ، حَدَّثَنَا يَحْيَى، - يَعْنِي ابْنَ سَعِيدٍ - عَنْ حَمَّادِ بْنِ سَلَمَةَ ، حَدَّثَنَا ثَابِتٌ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُغِيرُ إِذَا طَلَعَ الْفَجْرُ وَكَانَ يَسْتَمِعُ الأَذَانَ فَإِنْ سَمِعَ أَذَانًا أَمْسَكَ وَإِلاَّ أَغَارَ فَسَمِعَ رَجُلاً يَقُولُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " عَلَى الْفِطْرَةِ " . ثُمَّ قَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " خَرَجْتَ مِنَ النَّارِ " . فَنَظَرُوا فَإِذَا هُوَ رَاعِي مِعْزًى .
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.
