رَضُوا بِأَن يَكُونُوا مَعَ الْخَوَالِفِ وَطُبِعَ عَلَىٰ قُلُوبِهِمْ فَهُمْ لَا يَفْقَهُونَ (87)
(9:87) Those people chose to stay with those who had remained behind and a seal was set upon their hearts: therefore they do not understand anything now. *89
*89) "...they do not understand anything now," for they deliberately and intentionally chose the shameful way of staying at home with women, when they were required to go forth for Jihad, though they were healthy, physically fit and well-to-do, and professed Islam. Therefore, according to the Divine Law of Nature. a seal was set upon their hearts and they were bereft of those noble feelings which make one feel ashamed of adopting such a disgraceful conduct.
