Al Nisā’

أَمْ لَهُمْ نَصِيبٌ مِّنَ الْمُلْكِ فَإِذًا لاَّ يُؤْتُونَ النَّاسَ نَقِيرًا

53. "Or have they a share in the kingdom? Then in that case, they do not give even a speck to anybody!"

By the commentaries of the previous couple of verses, it was said that the Jews, to attract the attention of the idol-worshippers of Mecca, testified that the idolatry of the Quraysh was better than the theistic practice of the Muslims. Even they themselves fell prostration before the idols. In this verse, as well as the next one, this fact has been pointed out that their judgement was worthless and invalid. Each of these two verses contains a considerable proof.

In this verse the Qur'an inquires whether the Jews had any share in the government that they let themselves judge like that. And, yet, if they had such an authority, they would not give people any right when they might keep everything for themselves exclusively.
