لِّئَلَّا يَعْلَمَ أَهْلُ الْكِتَابِ (so that the People of the Book may know ....57:29) The negative particle la [ no ] is grammatically redundant [ but rhetorically it serves to emphasise the expression ]. This final verse states that the People of the Book need to know that faith in Prophet ` Isa (علیہ السلام) is not necessarily faith in the Prophet Muhammad ﷺ . In the circumstances, they do not deserve any Divine grace unless they embrace faith in the Last Prophet t. Allah, the Pure and Exalted, knows best!
