The word(s) "ra'ina" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) O you who believe! Say not (to the Messenger صلى الله عليه وسلم) ra'ina but say Unzurna (make us understand) and hear. And for the disbelievers there is a painful torment. (See Verse 4:46)

(2) Among those who are Jews, there are some who displace words from (their) right places and say: "We hear your word (O Muhammad صلى الله عليه وسلم and disobey," and "Hear and let you (O Muhammad صلى الله عليه وسلم) hear nothing." And ra'ina with a twist of their tongues and as a mockery of the religion (Islam). And if only they had said: "We hear and obey", and "Do make us understand," it would have been better for them, and more proper; but Allah has cursed them for their disbelief, so they believe not except a few.
