ٱلْمُنَافِقُون : ٣

  • ذَٰلِكَ That
  • بِأَنَّهُمۡ (is) because
  • ءَامَنُواْ they believed
  • ثُمَّ then
  • كَفَرُواْ they disbelieved;
  • فَطُبِعَ so were sealed
  • عَلَىٰ [upon]
  • قُلُوبِهِمۡ their hearts
  • فَهُمۡ so they
  • لَا (do) not
  • يَفۡقَهُونَ understand
That is because they believed, and then they disbelieved; so their hearts were sealed over, and they do not understand.
That, namely, their evil deed, is because they believed, by [affirming faith only with] the tongue, then disbelieved, in [their] hearts, that is to say, they persist in harbouring disbelief in it; therefore their hearts have been stamped, sealed, with disbelief. Hence they do not understand, faith.
