Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates that a Bedouin came to the Prophet (peace and blessings be upon him) and asked: «صور» What is it? The Prophet (peace and blessings be upon him) replied: “«صور» It is a horn in which it will be blown.”
