Tafsir of Al-Balad 90:18

"Those" is a demonstrative reference to the one mentioned, considering their description by that which is contained within the scope of the relative clause; and what it contains of the meaning of remoteness serves to elevate the status of the one referred to, for reasons previously mentioned more than once. That is: those described with the aforementioned magnificent attributes are "the companions of the right," meaning the side of the right, which is where the fortunate ones are, or the side of blessing (yumn), because they are blessed (mayamin) for themselves and for others.
