Narrated Uqbah ibn Amir: I heard the Messenger of Allah (peace be upon him) say: Allah is pleased with a shepherd of goats who calls to prayer at the peak of a mountain, and offers prayer, Allah, the Exalted, says: Look at this servant of Mine; he calls to prayer and offers it and he fears Me. So I forgive him and admit him to paradise.
Sunan Abi Dawud, Book 4, Hadith 6
