The title words appeared in Chapter 2 Verse 104 and then in Chapter 4 Verse 46. What is the exact meaning of word “Ra’ina” and “Onthurna”? Is there any precautions of using these words?

Re: Words "Ra'ina" and "Onthurna"
the jews used to mispronounce the word 'raiina' [hamaarii taraf bhii zaraaa iltifaat kijiiye] in a way that means a bad thing [derogatory] so, Huzoor [saws] instructed saHaaba-e-karaam [r.a.a.] to say 'unsurnaa' instead...effectively stopping the jews from mispronouncing the word and derogate our prophet [saws].
