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

“For, when they come unto you, they say, "We do believe": whereas, in fact, they come with the resolve to deny the truth, and depart in the same state. But God is fully aware of all that they would conceal.”

(When they) i.e. the lowly among the Jews; and it is also said this means the hypocrites (come unto you (Muslims), they say: We believe) in your traits and description which we find in our Scripture; (but they came in disbelief) they secretly disbelieve (and they went out in the same) disbelieving inwardly; (and Allah knoweth best what they were hiding) of disbelief.
