The steady boundary layer MHD stagnation- point flow past a stretching sheet through porous media with heat source /sink is investigated. The surface temperature of the sheet is taken time dependent. The governing equations are transformed into self-similar ordinary differential equations by adopting similarity transformations and then the converted equations are solved numerically by Runge-Kutta fourth order method. Special emphasis has been given to the parameters of physical interest which include velocity ratio parameter, Prandtl number, magnetic parameter, porous matrix,temperature index parameter and heat source parameter. The results obtained for velocity, temperature and skin friction are shown in tables and graphs. The comparison of the present results with the existing numerical solutions in a liming sense is also shown and this comparison is very good.
