Assalamualikum. Kindly be informed my daughter's name is Manha Laaibah Mashiur. I found "Manha" with a meaning of "Gift from Allah"; "Laaibah" with "the most beautiful woman in all Jannah who willl be in Jannat-ul-Firdous" & "Mashiur" is her father's first name. is it ok? Will appreciate if you kindly suggest the suitable name with similar meaning.
Answer
For Manha please see: Meaning and pronounciation of Manha. The meaning of "Gift from Allah" is incorrect, that's the meaning of Minha.
Laaibah is an incorrect pronunciation of Lu'bah/Loubah, which is the name of a Hoori mentioned in weak (unauthentic) hadith. Since it is not from an authentic hadith, this is likely false and fabricated. Lu'bah means "plaything", "toy", and it is not a very good name for a child. Laaibah means "player", one who plays a game, this too is not a very good meaning, since it could mean someone who doesn't take life seriously and who is always playing tricks.
You can use Laaibah or Loubah, as they are not forbidden in Islam, though I do not recommend them.
As for suggesting a suitable name, it is completely your own choice. Choose any name you like.
