Israel is Prophet Ya`qub, for Abu Dawud At-Tayalisi recorded that `Abdullah Ibn `Abbas said, "A group of Jews came to the Prophet and he said to them,

«هَلْ تَعْلَمُونَ أَنَّ إِسْرَائِيلَ يَعْقُوبُ؟»

(Do you know that Israel is Jacob) They said, "Yes, by Allah.'' He said,

«اللَّهُمَّ اشْهَد»

(O Allah! Be witness.)''

At-Tabari recorded that `Abdullah Ibn `Abbas said that `Israel' means, `the servant of Allah.'
