Surah Al-Ma'idah 5:61

وَإِذَا جَآءُوكُمْ قَالُوٓا۟ ءَامَنَّا وَقَد دَّخَلُوا۟ بِٱلْكُفْرِ وَهُمْ قَدْ خَرَجُوا۟ بِهِۦ ۚ وَٱللَّهُ أَعْلَمُ بِمَا كَانُوا۟ يَكْتُمُونَ

And when they come to you, they say, "We believe." But they have entered with disbelief [in their hearts], and they have certainly left with it. And Allāh is most knowing of what they were concealing.

Translation: Saheeh International

Tafsir

When they the hypocrites from among the Jews come to you they say ‘We believe’; but they have entered unto you ensconced in disbelief and so they have departed from you ensconced in it and they have not believed. And God knows very well what they were hiding of hypocrisy.
