In this work, time-dependent viscous fluid flow along a stretch plate with magnetohydrodynamic liquid filling the porous medium is considered. Energy expression consists of thermal radiation and viscous dissipation. By dimensionless variables, we transformed the governing model equations into non-dimensional form. Finite difference scheme is adopted for obtaining numerical solution, and variations in velocity, skin friction, temperature, and Nusselt number have been discussed and graphically illustrated using relevant flow parameters. According to our findings, velocity profile improves with Reynolds number and time but declines with Hartmann number and porosity parameter. Reynolds number, Prandtl number, and Eckert number increase the temperature profile and Nusselt number, whereas temperature decays with thermal radiation. Skin friction increases via porosity parameter, Hartmann number and suction parameter, while it reduces with Reynolds number.
