We study the detailed internal properties of a highly magnified ({\\mu}~29) z=4.88 galaxy seen through the cluster. We detect wide-spread nebular CIV{\\lambda}{\\lambda}1548,1551{\\AA} emission from this galaxy as well as a bright Ly{\\alpha} halo with a spatially-uniform wind and absorption profile across 12 kpc in the image plane. Blueshifted high- and low-ionisation interstellar absorption indicate the presence of a high-velocity outflow ({\\Delta}v~300 km/s) from the galaxy.
