"I heard the Messenger of Allah ﷺ say: 'Your Lord is pleased with a shepherd high in the mountains who calls the Adhan for the prayer and prays. Allah says: 'Look at this slave of Mine; he calls the Adhan and Iqamah for the prayer and fears Me. I have forgiven My slave and admitted him to Paradise.'" (Using translation from Nasāʾī 666)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ يَعْجَبُ رَبُّكَ مِنْ رَاعِي غَنَمٍ فِي رَأْسِ الشَّظِيَّةِ لِلْجَبَلِ يُؤَذِّنُ بِالصَّلَاةِ وَيُصَلِّي فَيَقُولُ اللهُ انْظُرُوا إِلَى عَبْدِي هَذَا يُؤَذِّنُ وَيُقِيمُ لِلصَّلَاةِ يَخَافُ مِنِّي قَدْ غَفَرْتُ لِعَبْدِي وَأَدْخَلْتُهُ الْجَنَّةَ
