عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((يَغْفِرُ اللَّهُ لِلْمُؤَذِّنِ مَدَّ صَوْتِهِ وَيَشْهَدُ لَهُ كُلُّ رَطْبٍ وَيَابِسٍ سَمِعَ صَوْتَهُ))
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty forgives the muezzin to the extent of the reach of his voice, and every moist and dry thing that hears his voice bears witness for him.
