﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَقُولُوا۟ رَٰعِنَا وَقُولُوا۟ ٱنظُرْنَا وَٱسْمَعُوا۟ ۗ وَلِلْكَٰفِرِينَ عَذَابٌ أَلِيمٌۭ ﴾

“O YOU who have attained to faith! Do not say [to the Prophet], "Listen to us," but rather say, "Have patience with us," and hearken [unto him], since grievous suffering awaits those who deny the truth.”

O you who believe do not say to the Prophet s ‘Observe us’ rā‘inā is an imperative form from murā‘āt which they used to say to him and this was a derogatory term in Hebrew derived from the noun al-ru‘ūna ‘thoughtlessness’. They found this very amusing and used to address the Prophet s in this way and so the believers were forbidden to use it; but say instead ‘Regard us’ that is look at us and give ear to what you are commanded and be prepared to accept it; and for disbelievers awaits a painful chastisement that is the Fire.
