assalam o alikum please help me I wanna give my baby girl name asmara which means "beautiful butterfly " but my husband says name meaning should not mention butterfly ............why? its nice name

Alaikumassalam wa rahmatullah,

For the meaning of Asmara please see this page: Raameen, Rania and Asmara, meaning and if Islamic or Quranic

The "beautiful butterfly" meaning you mentioned is not from Arabic. But if it is correct and it is from another language, there is no issue with it and you can use it. There is no prohibition in Islam from using butterfly in a name. Osama means lion and Uthman means snake. Farasha, the Arabic word for butterfly, is also a popular name for Muslim girls among Arabs.
