﴿ أَفَمَن يَمْشِى مُكِبًّا عَلَىٰ وَجْهِهِۦٓ أَهْدَىٰٓ أَمَّن يَمْشِى سَوِيًّا عَلَىٰ صِرَٰطٍۢ مُّسْتَقِيمٍۢ ﴾

“But then, is he that goes along with his face close to the ground better guided than he that walks upright on a straight way?”

Is he who walks cast down fallen on his face more rightly guided or he who walks upright on a straight path? the predicate of the second man ‘who’ has been omitted but is indicated by the predicate of the first namely ahdā ‘more rightly guided’; the similitude refers to the believer and the disbeliever and to which of the two is more rightly guided.
