And a group from amongst the later ones
Many from the later generations.
and a multitude of the later people
And a multitude from among those of later times
And a group from the others/lasts
… who joined the right path at the beginning and later
And a large group from the latter
And a large party from among the later ones
And from later generations will (also) be a large group (amongst them)
And a large party from the later ones
And a multitude of those (on the Right Hand) will be from the later times (generations)
