Your companion [Muhammad] has not strayed, nor has he erred,
Tafseer
{ ما ضل صاحبكم } محمد عليه الصلاة والسلام عن طريق الهداية { وما غوى } ما لابس الغي وهو جهل من اعتقاد فاسد .
{Your companion} Muhammad, peace and blessings be upon him, has not strayed from the path of guidance, {nor has he gone astray}, which is ignorance from a corrupt belief. {And he has not gone astray}.
