The sins mentioned here are among the many sins that the Jews committed, which caused
them to be cursed and removed far away from right guidance. The Jews broke the promises
and vows that Allah took from them, and also rejected Allah's Ayat, meaning His
signs and proofs, and the miracles that they witnessed at the hands of their Prophets.
Allah said,
﴿وَقَتْلِهِمُ الاٌّنْبِيَآءَ بِغَيْرِ
حَقٍّ﴾
(and their killing the Prophets unjustly,) because their many crimes and offenses
against the Prophets of Allah, for they killed many Prophets, may Allah's peace
be upon them Their saying:
﴿قُلُوبُنَا غُلْفٌ﴾
("Our hearts are Ghulf,'') meaning, wrapped with covering, according to Ibn `Abbas,
Mujahid, Sa`id bin Jubayr, `Ikrimah, As-Suddi and Qatadah. This is similar to the
what the idolators said,
﴿وَقَالُواْ قُلُوبُنَا فِى أَكِنَّةٍ
مِمَّا تَدْعُونَا إِلَيْهِ﴾
(And they say: "Our hearts are under coverings (screened) from that to which you
invite us.'') Allah said,
﴿بَلْ طَبَعَ اللَّهُ عَلَيْهَا بِكُفْرِهِمْ﴾
(nay, Allah has set a seal upon their hearts because of their disbelief,) It is
as if they had given an excuse that their hearts do not understand what the Prophet
says since their hearts are wrapped with coverings, so they claim. Allah said that
their hearts are sealed because of their disbelief, as we mentioned before in the
explanation of Surat Al-Baqarah. Allah then said,
﴿فَلاَ يُؤْمِنُونَ إِلاَّ قَلِيلاً﴾
(so they believe not but a little.) for their hearts became accustomed to Kufr,
transgression and weak faith.
