Why are the Majus mentioned in 22:17 but not in 6:23 of the Holy Quran?

2:62 : Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muhammad] – those [among them] who believed in Allah and the Last Day and did righteousness – will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve. 22:17 : Indeed, those who have believed and those who were Jews and the Sabeans and the Christians and the Magians and those who associated with Allah - Allah will judge between them on the Day of Resurrection. Indeed Allah is, over all things, Witness.
