Quran 7:33 – Why Does "Ithm" Mean “Usurping The Rights Of Others”?
In short, Ithm is used both in broader sense including all the sins and also in the specific sense of usurping someone’s rights. But whenever it is used in between different sins like in this case preceded by ‘Fawahish’ and succeeded by ‘Oppression’, then it always means the latter i.e. usurping someone’s rights.
