Translation of the verse 87 from Surah At-Taubah : Number of verses 129 - - page 201 - Part 10.
They are content to be with those (the women) who sit behind (at home). Their hearts are sealed up (from all kinds of goodness and right guidance), so they understand not.
They were satisfied to be with those who stay behind, and their hearts were sealed over, so they do not understand.
(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.
