57 and as to those who believe and do righteous works,
he will pay them their rewards (fully) and allah does not love the unjust.

commentary:
after the explanation about the first group, in this verse, it refers
to the second group and says:

"and as to those who believe and do righteous works,
he will pay them their rewards (fully),..."

then, in conclusion, it emphasizes again that:

"... and allah does not love the unjust."

thus, the lord, who does not love the unjust, will never treat
with the servants unjustly and will give them their rewards completely.
