It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "No man raises his voice in singing except that Allah sends two devils upon him who sit on his two shoulders and keep striking his chest with their heels until he falls silent, whenever he falls silent."
