And do not turn your cheek [in contempt] toward people and do (31:18)

Almuntakhab Fi Tafsir Alquran Alkarim

And do not, he continued, give cheek to people nor inflate it with pride and vanity nor should you walk on earth displaying inordinate self-esteem or with an overweening opinion of your qualities, attainments or estate. And do realize that Allah detests every boastful who exalts himself and displays inordinate self-esteem

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(31:18) Do not (contemptuously) turn your face away from people, *31 nor tread haughtily upon earth. Allah does not love the arrogant and the vainglorious. *32

And do not turn your cheek [in contempt] toward people and do meaning

*31) Tusa'ir in the original is from se 'ar. a disease in the camel's neck clue to which it keeps its face turned to one side. The idiom implies the attitude of a person who shows arrogance and vanity, turns his face away and treats others with scant respect.
*32) Mukhtal in the original implies a person who has an over-high opinion of himself, and fakhur is the one who boasts of his superiority over others. A man becomes haughty and arrogant and vain in his gait only when he is puffed up with pride, and wants that others should feel his superiority.
