In the second verse after that (45), there is a description of the injunctions of Qisas (Even Retaliation) with a particular reference stressing that ` We had revealed these injunctions in the Torah.' The words of the text are:
وَكَتَبْنَا عَلَيْهِمْ فِيهَا أَنَّ النَّفْسَ بِالنَّفْسِ وَالْعَيْنَ بِالْعَيْنِ وَالْأَنفَ بِالْأَنفِ وَالْأُذُنَ بِالْأُذُنِ وَالسِّنَّ بِالسِّنِّ وَالْجُرُوحَ قِصَاصٌ
` We had revealed in the Torah this injunction of Qisas for the Jews that there will be life for life, eye for eye, nose for nose, ear for ear, tooth for tooth; and for wounds an equal retaliation.'
It will be recalled that the case of Banu Qurayzah and Banu Nadir was brought before the Holy Prophet ﷺ . Counting on their power, Banu Nadir had compelled the weaker Banu Qurayzah to agree to their oppressive conditions which stipulated that should a man from Banu Qurayzah kill a man from Banu Nadir, they will have to pay two penalties. The Qisas of life for life will be taken as well as the blood money will have to be paid. If the case was the reverse, that is a man from Banu Nadir kills a man from Banu Qurayzah, then, there will be no Qisas; only blood money will be paid but that too will be half of what Banu Nadir were entitled to.
In this verse, Allah Almighty has exposed the lie of these people by pointing out that the injunctions of equality in Qisas (retaliation) and Diyat (blood money) exist in the Torah too. at these people are doing is considered avoidance and that they bring their case to the Holy Prophet ﷺ for a decision as alleged is no more than a ruse to find an excuse.
At the end of the verse it was said: وَمَن لَّمْ يَحْكُم بِمَا أَنزَلَ اللَّـهُ فَأُولَـٰئِكَ هُمُ الظَّالِمُونَ (And whoever does not judge by what Allah has sent down, then, they are the unjust.) It means that people who do not take the injunctions of Allah binding and who do not decide matters in accordance with them, are dissenters to the Divine commandment, its rejectors and rebels. They are unjust. The third verse (46) begins with the mention of the coming of Sayyidna ` Isa (علیہ السلام) who was sent to confirm the previous Scripture, that is, the Torah. Mentioned after that is the Injil because that too, like the Torah, is guidance and light.
