The jews call their state "Israel",the Quraan refered to the jews as children of "Israel" 1400 years ago

Israel is a Hebrew word, the equivalent of Abdullah in Arabic, which means the 'servant of Allah'.

This was the title given to Hadhrat Ya'coob (Alayhis salaam) by the Jews. He had 12 sons by which the Qur'aan makes reference to as 'al-Asbaat' (12 sons of Ya'coob) (Baqar Aayat136). The 12 tribes of Israel emerged from the progeny of these 12 sons. Hence, they are addressed in the Qur'aan as 'Banu Israaeel' (children of Israel, i.e. Ya'coob (Alayhis salaam)). So, it is clear that the Jews have been synonymous with the name Israel since before Nabi (Sallallaahu Alayhi Wasallam), thus, before the revelation of the Qur' aan.
