1. The title of Jacob is Israel in the Bible.
2. Please remember that all prophets are not named in the Qur'an. According to tradition, 124,000 prophets were sent to this planet. The tradition seems to be correct because the Qur'an tells us that every community had received its prophet/messenger/guide/warner of Allah. The first prophet/messenger was Noah. True, Israelite prophets descended from prophet Isaac.
There was no prophet in the lineage of prophet Ismail until 'khatam-al-anbiya' Muhammad (S).
16:36 We have raised in every community a Messenger, saying, “Serve God alone and shun false gods in any form.” Then God guided some of the people (since they followed the laws of guidance 4:88). And error took hold of others (who fell into arrogance or blind following 18:29). So, travel through the earth, and see what the end was of the deniers.
13:7 Those who deny the truth keep saying, "Why has no miracle ever been bestowed upon him from his Lord?" But you (O Prophet) are only a warner and to every community is a guide. [The Perfect Divine Guidance through the Prophet shall be preserved in the form of the Qur’an for all times and all people 6:34, 6:91-92, 6:116, 10:64, 15:9 18:27, 41:53, 75:16-19]
