Sayyiduna Abu Umamah al-Bahili (may Allah be pleased with him) narrates this from a person who saw the Prophet (peace and blessings be upon him) when he was going to Mina on the Day of Tarwiyah. Sayyiduna Bilal (may Allah be pleased with him) was beside him, holding a stick with a cloth attached to it, with which he was shading the Prophet (peace and blessings be upon him).
Ahmad recorded it in this way.
