وَإِذَا لَقُوا الَّذِينَ آمَنُوا قَالُوا آمَنَّا وَإِذَا خَلَا بَعْضُهُمْ إِلَى بَعْضٍ قَالُوا أَتُحَدِّثُونَهُم بِمَا فَتَحَ اللَّهُ عَلَيْكُمْ لِيُحَاجُّوكُم بِهِ عِندَ رَبِّكُمْ أَفَلَا تَعْقِلُونَ
When they meet the faithful, they say, ‘We believe,’ and when they are alone with one another, they say, ‘Do you recount to them what Allah has revealed to you, so that they may argue with you therewith before your Lord? Do you not exercise your reason?’
Agha Ali Puya Commentary
Commentary on Quran 2:76
[Pooya/Ali Commentary 2:76] Those Jews, who only pretended to have accepted Islam, had close relations with the rabbis. In their meetings, the clever rabbis, as stated in the commentary of Baqarah: 42, reprimanded the less-careful converts for their unscrupulous utterings about the prophecies written in their scriptures regarding the advent of the Holy Prophet. They were afraid of giving the believers, through such disclosures, an upper hand at the time of argumentation, which could make the true seekers of the truth among them go into the fold of Islam in sincerity.
