3-Surah Al-Imran ( The Family of Imran ) 86
How shall Allah guide a people who disbelieved after their belief and had witnessed that the Messenger is true and clear signs had come to them? And Allah does not guide the wrongdoing people.
كَيْفَ يَهْدِي اللَّهُ قَوْمًا كَفَرُوا بَعْدَ إِيمَانِهِمْ وَشَهِدُوا أَنَّ الرَّسُولَ حَقٌّ وَجَاءَهُمُ الْبَيِّنَاتُ ۚ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الظَّالِمِينَ
Quran's Tafhim ( explanation)
*73). This is a repetition of the statement made earlier, namely that the Jewish rabbis of Arabia in the time of the Prophet (peace be on him) knew, and sometimes even testified to verbally, that Muhammad was a true Prophet and that his teachings were the same as those of the earlier Prophets. (See for instance Qur'an 2: 89 - Ed.) Their subsequent attitude - namely that of rejection and opposition - was the outcome of prejudice and intransigence, born out of their centuries-old hostility to the Truth.
