﴿ وَبِكُفْرِهِمْ وَقَوْلِهِمْ عَلَىٰ مَرْيَمَ بُهْتَٰنًا عَظِيمًۭا ﴾

“and for their refusal to acknowledge the truth, and the awesome calumny which they utter against Mary,”

The Jews had Scriptures revealed to them in which they were asked to surrender to the will of God in this world, in return for which God would grant them Paradise in the next. They forgot the first part and came to regard the second part as their birthright. All kinds of rot set in among the Jewish community. Moreover, they were so greatly convinced of the notion that salvation was their birthright that they considered it unnecessary to acknowledge the new Prophet. They would say ironically, ‘Our hearts are sealed.’ This not only showed their inability to acknowledge the new Prophet, but also their conviction that, whatever their misconduct with the Prophet, their salvation was not going to be endangered.
