It is narrated from Uqbah bin Amir (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Your Lord marvels at a shepherd of goats on a high mountain peak who gives the adhan for the prayer and prays. Then Allah Almighty says: 'Look at this servant of Mine; he gives the adhan and the iqamah for the prayer, fearing Me. I have forgiven My servant and admitted him into Paradise.'"
