28:77-78

28:77
“But seek, with the (wealth) which Allah has bestowed
on thee, the Home of the Hereafter, nor forget
thy portion in this world: but do thou good, as Allah has
been good to thee, and seek not (occasions
for) mischief in the land: for Allah loves not those who
do mischief.”
28:78
He said: “This has been given to me because of a certain
knowledge which I have.” Did he not know
that Allah had destroyed, before him, (whole)
generations,- which were superior to him in strength and
greater in the amount (of riches) they had collected? but
the wicked are not called (immediately) to
account for their sins.
