Not only does "Allah" just mean god, it is definitely referring to the *same* Abrahamic god Christians worship.

Muslims believe the other "people of the book" had their traditions corrupted, and Islam is the perfected and final message - a continuation of the same lineage. https://twitter.com/AubreyGilleran/status/1264413707876122626

Muslims believe god has attempted to give us his message many times, but humans variously corrupted that message. It is *Allah* who sent Abraham (Ibrahim), Moses (Musa), Noah (Nuh), Jesus (Isa)...and Lot, David, John, Jonah...

But they were not heeded. Thus, the "seal", big Mo.

Non-Muslims don't appreciate the similarities between Quranic lore and the Bible.

Also, while the timeline is Judaism > Christianity > Islam, the latter was definitely far more influenced by Judaism.

In terms of relation, Judaism = parent, Christianity big bro, Islam lil bro.
