It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) used to perform the Asr prayer when the sun was bright and in the shape of its disc. I would reach my neighborhood and house located in a corner of Madinah Munawwarah and would tell them that the Prophet (peace and blessings be upon him) has already performed the prayer, so you should also get up and perform the prayer.
