We examine the effect of MHD flow of the Casson nanofluid model on heat and mass transfer over a stretching sheet with Thompson and Trioan slip boundary condition. The relaxation properties of the fluid flow are studied by using the Cattaneo-Christov heat flux model. The governing partial differential equations are transformed into self-similar form and solved numerically by using the spectral collocation method. The effects of various fluid parameters on velocity profile, temperature profile, and nanoparticle concentration, are discussed. The results reveal that the enhancement of the thermal relaxation parameter reduces the temperature of the fluid. Furthermore, the temperature increases when temperature ratio, thermal radiation, Biot number, Eckert number, and Casson parameter are increased. A comparative study with earlier results is made. Skin friction, local Nusselt number and local Sherwood number are analyzed.
