It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him): "The Messenger of Allah (peace and blessings be upon him) set out from Mina towards Makkah on the Day of Tarwiyah, and he (peace and blessings be upon him) arrived with Sayyiduna Bilal (may Allah be pleased with him) at his side, holding a cloth on a stick with which he was shading him (peace and blessings be upon him) from the heat of the sun."
