Can you provide a website for good Islamic names, and what is the ruling on naming a daughter "Mona" and a son "Nimra"?

It is recommended to choose beloved legitimate names such as Abdullah and Abdurrahman, names of male and female companions (Sahaba and Sahabiyat), and well-known Arabic names. One should avoid unfamiliar names that might lead to forbidden acts, or names of places of worship and sacred sites.
