Salam. My name is Hasham rehman. I'm not into islam a lot but I want to. I have a question and which is?

In Quran its said there were 125000 messengers. But no one knows even the name on them. Not even in Quran its written. My mom said those messengers may be in different planets or different place than earth. If it is true so I have this thing in my mind.

Quran came on Holy Prophet (P.B.U.H) and Quran is the one and only book ob muslims. So the Holy Prophet was born on Earth so that's y The Quran came in the world but if its true that other messengers may have been in different place then earth so there won't be any muslim there because there won't be Quran. I'm so curious about this and couldn't find the right answer so finally after a long time now I'm discussing it with you.
Thanks,

Salaams,

Those messengers were not sent to some other planets.
Your mother's assumption is wrong.

Okkk. But if they were sent to earth does anyone in world even know all their names ?

No, we do not. But Muslims do believe they were all sent by Allah to guide people to the straight path. We only know about some of them from the Holly Qur'aan.
