الآية رقم (73) - وَلاَ تُؤْمِنُواْ إِلاَّ لِمَن تَبِعَ دِينَكُمْ قُلْ إِنَّ الْهُدَى هُدَى اللّهِ أَن يُؤْتَى أَحَدٌ مِّثْلَ مَا أُوتِيتُمْ أَوْ يُحَآجُّوكُمْ عِندَ رَبِّكُمْ قُلْ إِنَّ الْفَضْلَ بِيَدِ اللّهِ يُؤْتِيهِ مَن يَشَاء وَاللّهُ وَاسِعٌ عَلِيمٌ

(73) - (And do not trust except those who follow your religion." Say, "Indeed, the [true] guidance is the guidance of Allah. [Do you fear] lest someone be given [knowledge] like you were given or that they would [thereby] argue with you before your Lord?" Say, "Indeed, [all] bounty is in the hand of Allah - He grants it to whom He wills. And Allah is all-Encompassing and Wise.")

The Almighty unveils the attempt of the Jews to deceive the Prophet (saws) and the believers by claiming belief at the beginning of the day and disbelieving at it’s end. The plotters asked each other to keep it secret in order not to deviate from the ultimate goal -to shake the illiterate Muslims. So, they wanted to reveal it only to people like them, but the Almighty has revealed their plot by revealing this verse to Prophet Muhammad (saws).
