  Abell 1351 is a massive merging cluster that hosts a giant radio halo and a
bright radio edge blended in the halo. In this paper, we present the first ever
spectral analysis of this cluster using GMRT 610 MHz and VLA 1.4 GHz archival
data and discuss the radio edge property. Using \textit{Chandra} data, we
report the first tentative detection of shock front at the location of the edge
in A1351 with discontinuities in both X-ray surface brightness and temperature.
Our analysis strengthens the previous claim of the detected "edge" being a high
luminosity radio relic. The radio relic has an integrated spectral index
$\alpha = -1.63 \pm 0.33$ and radio power $P_{1.4 \mathrm{\ GHz}} = 4.46 \pm
0.61\times10^{24}$ W $Hz^{-1}$ with a largest Linear Size (LLS) of 570 kpc. The
radio spectral index map shows steepening in the shock downstream region. Our
analysis favours the scenario where the Diffusive Shock Acceleration (DSA) of
particles is responsible for the origin of the radio relic in the presence of
strong magnetic field. We have also estimated the magnetic field at the relic
location assuming equipartition condition.
