Allah tells us about His Book and the guidance, proof and criterion between right and wrong that it contains. He tells us about the Children of Israel, who were the bearers of the Tawrah and Injil.

[أَكْثَرَ الَّذِى هُمْ فِيهِ يَخْتَلِفُونَ]

(most of that in which they differ.) such as their different opinions about `Isa. The Jews lied about him while the Christians exaggerated in praise for him, so the Qur'an came with the moderate word of truth and justice: that he was one of the servants of Allah, and one of His noble Prophets and Messengers, may the best of peace and blessings be upon him, as the Qur'an says:

[ذلِكَ عِيسَى ابْنُ مَرْيَمَ قَوْلَ الْحَقِّ الَّذِى فِيهِ يَمْتُرُونَ ]

(Such is `Isa, son of Maryam. (It is) a statement of truth, about which they doubt) (19:34).

[وَإِنَّهُ لَهُدًى وَرَحْمَةٌ لِّلْمُؤمِنِينَ ]

(And truly, it is a guide and a mercy for the believers.) meaning, it is guidance for the hearts of those who believe in it, and a mercy to them. Then Allah says:

[إِن رَبَّكَ يَقْضِى بَيْنَهُم]

(Verily, your Lord will decide between them) meaning, on the Day of Resurrection,

[بِحُكْمِهِ وَهُوَ الْعَزِيزُ]

(by His judgement. And He is the All-Mighty,) means, in His vengeance,

[الْعَلِيمُ]

(the All-Knowing.) Who knows all that His servants do and say.
