Hope you doing well; the Noble Quran (the true book from Allah for all human being, which is NOT at all tempered and modified to DATE and cannot be changed as Allah directly is protecting His statements) confirms that the belief (Deen) of all the messengers is the same.

I took the liberty of translating the names of the messengers mentioned in the Quran in English to be more familiar.

Adam, Abraham, Isaac, Idris, Ishmael, Elisha, Job, Lot, Noah, Saleh, Shoaib, Solomon, Jacob, Joseph, Johan, Dhul Kifl, Hud, Elias, Zechariah, Moses, Aaron, Jesus and Muhammad (Peace & Blessings to all)

(Some of the names might have been missed and are not mentioned in sequence of arrival as per the timelines/history, due to my mistake as am writing the names from my memory, please excuse that)

So they all followed one true religion that was and is Islam....

You are welcome to do your research and confirm the statements from the Noble Quran (the last book of Allah for ALL humans to get benefit from and attain pleasure of the Lord, Allah)

Hope this helps & Allah knows the best
