It is narrated from Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him), he says: We used to perform the Zuhr prayer with the Noble Prophet (peace and blessings be upon him) at the intense heat of midday, but then the Prophet (peace and blessings be upon him) instructed us: Perform this prayer after letting it cool down, for indeed, intense heat is from the steam of Hell.
