Changing one's son's name
Q: My son was born on 29th July 2017 between 8:00AM and 8:45 AM. I named him Mir Mohammad Ashar. But recently a Mufti told me to change his name as the name Ashar has no meaning, it means counting in Arabic.
Now I want to change my son name to Mir Mohammad Ebrahim. It is ok and permissible in Islam to change the name and what is the procedure to change.
