Some people call their children by names from aayahs of the Qur’aan, such as Afnaan and Aalaa, etc. What is your opinion?

Praise be to Allaah. 

There is nothing wrong with
that, for these are created things. Aalaa’ means blessings and Afnaan
means branches. People have started to look for more variety in names and
are looking for new names for their sons and daughters.
