Surah Al-A'raf, Ayah 159

There is a group from the people of Moses amongst the Israelites who stand for the truth, and guide people to it, and who are just in their rulings between people through it.

And of the people of Musa there is a community who lead (the men) with truth and establish justice therewith (159)

Allah stated that of the Children of Israel there are some who follow the truth and judge by it, just as He said in another Ayah,

مِّنْ أَهْلِ الْكِتَابِ أُمَّةٌ قَائِمَةٌ يَتْلُونَ آيَاتِ اللَّهِ آنَاءَ اللَّيْلِ وَهُمْ يَسْجُدُونَ

(A party of the people of the Scripture stand for the right, they recite the verses of Allah during the hours of the night, prostrating themselves in prayer)[3:113],

وَإِنَّ مِنْ أَهْلِ الْكِتَابِ لَمَن يُؤْمِنُ بِاللَّهِ وَمَا أُنزِلَ إِلَيْكُمْ وَمَا أُنزِلَ إِلَيْهِمْ خَاشِعِينَ لِلَّهِ لَا يَشْتَرُونَ بِآيَاتِ اللَّهِ ثَمَنًا قَلِيلًا أُولَٰئِكَ لَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ إِنَّ اللَّهَ سَرِيعُ الْحِسَابِ

(And there are, certainly, among the People of the Scripture, those who believe in Allah and in that which has been revealed to you, and in that which has been revealed to them, humbling themselves before Allah. They do not sell the verses of Allah for a small price, for them is a reward with their Lord. Surely, Allah is Swift in account.)[3:199]

الَّذِينَ آتَيْنَاهُمُ الْكِتَابَ مِن قَبْلِهِ هُم بِهِ يُؤْمِنُونَ - وَإِذَا يُتْلَىٰ عَلَيْهِمْ قَالُوا آمَنَّا بِهِ إِنَّهُ الْحَقُّ مِن رَّبِّنَا إِنَّا كُنَّا مِن قَبْلِهِ مُسْلِمِينَ - أُولَٰئِكَ يُؤْتَوْنَ أَجْرَهُم مَّرَّتَيْنِ بِمَا صَبَرُوا

(Those to whom We gave the Scripture before it, they believe in it (the Qur'an). And when it is recited to them, they say: "We believe in it. Verily, it is the truth from our Lord. Indeed even before it we have been from those who submit themselves. These will be given their reward twice over, because they are patient.)[28:52-54], and,

إِنَّ الَّذِينَ أُوتُوا الْعِلْمَ مِن قَبْلِهِ إِذَا يُتْلَىٰ عَلَيْهِمْ يَخِرُّونَ لِلْأَذْقَانِ سُجَّدًا - وَيَقُولُونَ سُبْحَانَ رَبِّنَا إِن كَانَ وَعْدُ رَبِّنَا لَمَفْعُولًا - وَيَخِرُّونَ لِلْأَذْقَانِ يَبْكُونَ وَيَزِيدُهُمْ خُشُوعًا

(Verily, those who were given knowledge before it, when it (this Qur'an) is recited to them, fall down on their faces in humble prostration. And they say: "Glory be to our Lord! Truly, the promise of our Lord must be fulfilled." And they fall down on their faces weeping and it increases their humility.)[17:107-109]
