That assumption does contradict with Rumi’s When everything seems to oppose you
And who knows what’s inside their hearts? after all you judge people by looking at their actions not with assumptions. The last sentence of first quote that says do what is right is the check, IMO.
Ok. You can relate Rumi’s quote to some ayah, but it could be your own understanding. Infact, unlike first quote, Rumi’s quote does not require you to know what you do is right or wrong.
