[Machine] The Prophet ﷺ went out one day with Abu Bakr, Umar, Zaid bin Thabit, Abdullah bin Masood, Ubayy bin Ka'b and Abdullah bin Abbas, and the Prophet ﷺ was riding on his gray mule. When they appeared, the Prophet ﷺ heard a man saying, "Allahu Akbar, Allahu Akbar" (Allah is the greatest, Allah is the greatest). So he stood still and listened. When the man said, "Allahu Akbar, Allahu Akbar," the Messenger of Allah ﷺ said, "Bear witness to this by the One in whose hand is my soul, with the testimony of truth." When he said, "I bear witness that there is no god but Allah," the Messenger of Allah ﷺ said, "He is free from the Fire, by the One in whose hand is my soul," three times. Then the Messenger of Allah ﷺ said, "This man is the companion of some dogs." So Ibn Mas'ud and Ibn Abbas went and found him like that.  

خَرَجَ النَّبِيُّ ﷺ ذَاتَ يَوْمٍ وَمَعَهُ أَبُو بَكْرٍ وَعُمَرُ وَزَيْدُ بْنُ ثَابِتٍ وَعَبْدُ اللهِ بْنُ مَسْعُودٍ وَأُبَيُّ بْنُ كَعْبٍ وَعَبْدُ اللهِ بْنُ عَبَّاسٍ وَالنَّبِيُّ ﷺ عَلَى رَاحِلَتِهِ الْجَدْعَاءِ فَلَمَّا بَرَزُوا سَمِعَ النَّبِيُّ ﷺ رَجُلًا يَقُولُ اللهُ أَكْبَرُ اللهُ أَكْبَرُ فَوَقَفَ يَسْتَمِعُ فَلَمَّا قَالَ اللهُ أَكْبَرُ اللهُ أَكْبَرُ قَالَ رَسُولُ اللهِ ﷺ «شَهِدَ هَذَا وَالَّذِي نَفْسِي بِيَدِهِ بِشَهَادَةِ الْحَقِّ» فَلَمَّا قَالَ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ قَالَ «بَرِئَ هَذَا وَالَّذِي نَفْسِي بِيَدِهِ مِنَ النَّارِ» ثَلَاثَ مَرَّاتٍ ثُمَّ قَالَ رَسُولُ اللهِ ﷺ «هَذَا صَاحِبُ كِلَابٍ» فَذَهَبَ ابْنُ مَسْعُودٍ وَابْنُ عَبَّاسٍ فَوَجَدُوهُ كَذَلِكَ
