Translation of the verse 140 from Surah Al-Baqarah : Number of verses 286 - - page 21 - Part 1.
Or say you that Ibrahim (Abraham), Isma'il (Ishmael), Ishaque (Isaac), Ya'qub (Jacob) and Al-Asbat [the twelve sons of Ya'qub (Jacob)] were Jews or Christians? Say, "Do you know better or does Allah (knows better that they all were Muslims)? And who is more unjust than he who conceals the testimony [i.e. to believe in Prophet Muhammad Peace be upon him when he comes, written in their Books. (See Verse 7:157)] he has from Allah? And Allah is not unaware of what you do."
Or do you say that Abraham and Ishmael and Isaac and Jacob and the Descendants were Jews or Christians? Say, "Are you more knowing or is Allah?" And who is more unjust than one who conceals a testimony he has from Allah? And Allah is not unaware of what you do.
(2:140) Or do you say that Abraham. Ismail , Isaac, Jacob and his children were all Jews or Christians?" Ask them,"Do you know more than Allah does? *140 And who is more unjust than the one who hides the testimony which Allah has entrusted to him? Allah is not unaware of what you are doing. *141
*140). This remark is addressed to the ignorant mass of Jews and Christians who sincerely believed that all the Prophets belonged to their religious denomination.
*141). This remark is addressed to the Jewish and Christian theologians who were not unaware that Judaism and Christianity, with their existing characteristics, had emerged at a relatively late period in history. They nevertheless considered Truth to he confined to their own religious sects. They also perpetuated the misunderstanding that man's ultimate happiness and success lay in following the beliefs, institutions and legal codes which had been developed by their jurists, theologians and mystics long after the Prophet of God had passed away. When these theologians were asked to which among their religious communities Abraham, Isaac, Jacob and other Prophets belonged, they evaded a reply. This was because they could not state categorically that they belonged to their own sect. On the other hand, they could not reply explicitly in the negative, for such an admission would have undermined the very basis of their claim that Truth was confined to their fold.
