Injustice against Yourselves (Surah Yunus 10:23)

O mankind! Your rebellion (disobedience to Allah) is only against yourselves, it is you yourselves that will taste the evil consequence of this transgression. You will not harm anyone else with it, as comes in the Hadith,

There is no sin that is more worthy that Allah hasten punishment for in this world -- on top of the punishment that Allah has in store for it in the Hereafter -- than oppression and cutting the ties of the womb. Allah's statement:

a brief enjoyment of this worldly life... means that you only have a short enjoyment in this low and abased worldly life.

then (in the end) unto Us is your return... meaning your goal and final destination.

and We shall inform you of all your deeds. Then we shall recompense you for them. So let him who finds good (in his record) praise Allah, and let him who finds other than that blame no one but himself.
