Hadith 1661
Sayyiduna Abdur Rahman bin Abdullah narrates from his father: Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) said to him, "I have seen that you like to live among sheep and goats and prefer a rural life (the narrator is in doubt, or perhaps these are the words), or you live among sheep and goats and in the wilderness. So, give the call to prayer (adhan) and raise your voice while giving the adhan, for wherever the voice of the muezzin reaches, whatever jinn, human, or anything else hears it, it will bear witness in favor of that muezzin on the Day of Resurrection." Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) said, "I heard the Prophet Muhammad (peace and blessings be upon him) say this."
