Hi can I know is it right to change name if it doesn't suit u n wat does zarafshan mean is it a perfect suit to surname tariq n at does kulsoom mean?

I have answered the question about Zarafshan on this page, please take a look at it: Best names among Musfirah Zarafshan Eshal Inaya Arfa Narmeen Sehrish

Kulsoom, also pronounced Kalsoom, Kulthum, and Kalthoom is a non-Quranic Arabic name for girls that means a girl with full healthy cheeks. A variant of this name is Umm Kulsoom, which was the name of one of the Prophet's daughters, peace and blessings of Allah upon him and his family and companions.
