It was narrated that 'Uqbah bin 'Amir said:
"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.'" (FR)
