But those who disbelieved in Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), they are those on the Left Hand (the dwellers of Hell).
As for those who reject Our verses, they are the People of the Left Hand. (i.e. their books of deeds will be given in their left hands.)

But those who reject Our Signs, they are the (unhappy) Companions of the Left Hand.
