The Prophet ﷺ said: The mu'adhdhin will receive forgiveness to the extent to which his voice reaches, and every moist and dry place will testify on his behalf; and he who attends (the congregation of) prayer will have twenty-five prayers recorded for him and will have expiation for sins committed between every two times of prayer. (Using translation from Abū Dāʾūd 515)   

أَنَّهُ سَمِعَ مِنْ فَمِ رَسُولِ اللهِ ﷺ يَقُولُ الْمُؤَذِّنُ يُغْفَرُ لَهُ مَدَّ صَوْتِهِ وَيَشْهَدُ لَهُ كُلُّ رَطْبٍ وَيَابِسٍ وَشَاهِدُ الصَّلَاةِ يُكْتَبُ لَهُ خَمْسٌ وَعِشْرُونَ حَسَنَةً وَيُكَفَّرُ عَنْهُ مَا بَيْنَهُمَا  

[Machine] The Messenger of Allah ﷺ said, "Allah forgives the Muadhin (the one who calls for prayer) for the sounds he makes, and every moist and dry object bears witness to his voice."  

قَالَ رَسُولُ اللهِ ﷺ يَغْفِرُ اللهُ لِلْمُؤَذِّنِمَدَّ صَوْتِهِ وَيَشْهَدُ لَهُ كُلُّ رَطْبٍ وَيَابِسٍ سَمِعَ صَوْتَهُ  

[Machine] The Messenger of Allah ﷺ said, "The muezzin has his sins forgiven as long as he extends his voice and every moist and dry thing testifies for him."  

قَالَ رَسُولُ اللهِ ﷺ «الْمُؤَذِّنُ يُغْفَرُ لَهُ مَدَّ صَوْتِهِ وَيَشْهَدُّ لَهُ كُلُّ رَطْبٍ وَيَابِسٍ»  

"The Mu'adhdhin will be forgiven as far as his voice reaches, and every wet and dry thing will bear witness for him." (Using translation from Nasāʾī 645)  

عَنْ أَبِي هُرَيْرَةَ سَمِعَهُ مِنْ فَمِ النَّبِيِّ ﷺ يَقُولُ «الْمُؤَذِّنُ يُغْفَرُ لَهُ مُدَّ صَوْتِهِ وَيَشْهُدُ لَهُ كُلُّ رَطْبٍ وَيَابِسٍ»  

[Machine] The Messenger of Allah ﷺ said, "The one who calls the Adhan will be forgiven for as far as his voice reaches, and every moist and dry thing that hears him will bear witness for him." This narration was reported by Hafs ibn Ghayath.  

قَالَ رَسُولُ اللهِ ﷺ يُغْفَرُ لِلْمُؤَذِّنِ مَدَى صَوْتِهِ وَيَشْهَدُ لَهُ كُلُّ رَطْبٍ وَيَابِسٍ سَمِعَهُ وَرَوَاهُ حَفْصُ بْنُ غِيَاثٍ  

"المُؤَذِّنُ يُغْفَرُ لَهُ مَدَّ صَوْتِه، ويَشْهَدُ لَهُ كُلُّ مَنْ سَمِعَ صَوْتَهُ مِنْ رَطبٍ أو يَابِس" .  

"الْمُؤَذِّنُ يُغْفَرُ لَهُ مَدَّ صَوْتِهِ، وَيَشْهَدُ لَهُ كُلُّ مَدرِةِ أَو شَجَرَةَ سَمِعَتْ صَوْتَهُ".
