Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) says: We were on a journey with the Messenger of Allah (peace and blessings be upon him), and we heard a caller giving the adhan, saying: Allahu Akbar, Allahu Akbar. When the Noble Prophet (peace and blessings be upon him) heard these words, he said: This person is upon the natural disposition (fitrah) of Islam. Then when he said: Ashhadu an la ilaha illallah, the Prophet of Allah (peace and blessings be upon him) said: He has been saved from (the fire of) Hell. Then we hurried towards him, and he was a shepherd of animals, whom the prayer had reached, so he gave the adhan.
