In the second verse At-Tawbah 9:30 ⧉, the subject taken up briefly in At-Tawbah 9:29 ⧉ (where it was said that these people do not believe in Allah) has been enlarged. In the second verse, it has been said that the Jews take Sayyidna ` Uzayr (علیہ السلام) to be the Son of God.l So do the Christians. They say that Sayyidna ` Isa (علیہ السلام) is the Son of God. Therefore, their claim that Allah is One and that they have faith turns out to be false.
1. This is not the belief of all the Jews; it was the belief of some Jews of the Arabia. Now, the Dead Sea Scrolls have also proved the fact that some Jewish sects believed Ezra to be the son of God. It is learnt from some scholars who have studied the Scrolls. وَاللہُ اعلم ، (Muhammad Taqi Usmani)
After that, it was said: ذَٰلِكَ قَوْلُهُم بِأَفْوَاهِهِمْ. (That is their saying [ invented ] by their mouths). This could also mean that these people profess it openly and clearly through their own tongues. There is nothing secret about it. Then, it could also mean that this blasphemy they utter re-mains the work of their tongues. They can give no reason or justification for it.
Finally, it was said: یضَاهِئُونَ قَوْلَ الَّذِينَ كَفَرُوا مِن قَبْلُ ۚ قَاتَلَهُمُ اللَّـهُ ۚ أَنَّىٰ يُؤْفَكُونَ (They (They resemble the earlier disbelievers in their saying. Be they killed by Allah, how far turned away they are! ). It means that the Jews and Christians, by calling prophets sons of Allah, became the same as disbelievers and Mushriks of past ages, for they used to say that the angels, and their idols, Lat and Manat, were daughters of God.
