Is it permissible for the husband to view the face of his wife after her death and can he assist in the burial process?

It is permissible for a husband to view the face of his wife after her demise. He may also assist in the burial procedure, e.g. lowering the body in the grave, etc.

However, direct skin contact after the demise of his wife is not permissible as the Nikah has terminated. (Ahsanul Fataawa vol.4 pg.225)

and Allah Ta'ala Knows Best
