31.“The right side of the Mount”means the eastern side of the mountain. As Prophet Moses (peace be upon him), on his way from Midian to Egypt, was passing from the southern side of Mountt Toor, the eastern side would lie on his right and the western on his left if he faced the mountain, otherwise a mountain by itself cannot have a right or a left side.
32. See(E.N. 206 of Surah An-Nisa).
