Hi Kanade!
In the Bible Jesus states the truth of the missions of Abraham, Noah, Moses, Elijah and the other prophets of the Tanakh, as well as John the Baptist. And so all Christians accept those prophets as true.
In similar fashion, the Bahaâi Writings affirm the truth of all those prophets accepted by Christians as well as the Sonship of Jesus, the mission of Muhammad, the validity of Zoroaster (btw, the Magi who came to honor the newborn Jesus were probably Zoroastrian priests), the truth of Krishna (Hinduism) and the message of Guatama Buddha. The Bahaâi Scriptures also affirm that there were many other true prophets of God, and that no people nor place in the world was ever left without Divine guidance.
The Bahaâi canon of official doctrine and interpretation is now closed since the passing of Shoghi Effendi, but as individuals many Bahaâis also believe that Guru Nanak (founder of Sikhism), White Calf Buffalo Woman and the Great Peacemaker (Deganawida) in North America, and CÄ Äcatl Topiltzin QuetzalCoatl in South America were also prophets from God to their respective peoples and cultures.
As a practical matter, Bahaâis seek a relationship of friendliness and fellowship with all religions and their followers. That is certainly not to ignore or deny that some sects and religious leaders have strayed utterly far from God, embracing violence and hatred and antipathy towards those who believe differently. These words are attributed to Abduâl-Baha, son of Bahaâuâllah:
âIf religion becomes a cause of dislike, hatred and division, it were better to be without it, and to withdraw from such a religion would be a truly religious act.â

I hope this answered your question.
