The Quran

مِنَ الَّذينَ هادوا يُحَرِّفونَ الكَلِمَ عَن مَواضِعِهِ وَيَقولونَ سَمِعنا وَعَصَينا وَاسمَع غَيرَ مُسمَعٍ وَراعِنا لَيًّا بِأَلسِنَتِهِم وَطَعنًا فِي الدّينِ ۚ وَلَو أَنَّهُم قالوا سَمِعنا وَأَطَعنا وَاسمَع وَانظُرنا لَكانَ خَيرًا لَهُم وَأَقوَمَ وَلٰكِن لَعَنَهُمُ اللَّهُ بِكُفرِهِم فَلا يُؤمِنونَ إِلّا قَليلًا

N. J. Dawood

Some Jews take words out of their context and say:¹ ‘We hear, but disobey. May you be bereft of hearing! Rā‘inā!’ — thus distorting the phrase with their tongues and reviling the true faith. But if they said: ‘We hear and obey: hear us and Unzurnā,’² it would be better and more proper for them. God has cursed them in their unbelief. They have no faith, except a few of them.

To Muḥammad
The words mean ‘Listen to us’ and ‘Look upon us’ respectively; but in Judaeo-Arabic the sound of the first conveys the sense, ‘Our evil one’. Arabian Jews used the expression as a derisive pun.
