Al-Bara’ ibn ‘Azib reported: The Prophet, peace and blessings be upon him, said, “Verily, the angels send blessings upon those in the first row of prayer. The caller to prayer is forgiven for as far as his voice reaches and his truthfulness is affirmed by whichever creature hear him, wet or dry. He will have a reward similar to those who pray with him.”

عَنْ الْبَرَاءِ بْنِ عَازِبٍ أَنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ اللَّهَ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى الصَّفِّ الْمُقَدَّمِ وَالْمُؤَذِّنُ يُغْفَرُ لَهُ بِمَدِّ صَوْتِهِ وَيُصَدِّقُهُ مَنْ سَمِعَهُ مِنْ رَطْبٍ وَيَابِسٍ وَلَهُ مِثْلُ أَجْرِ مَنْ صَلَّى مَعَهُ
