Is it permissible to name a newborn female "Saḥāb"? Is it a common name or specific to females? Was any of the female Companions, female Successors, or righteous women known by this name?

It is recommended to name children with good names. It is permissible to name a female "Sahab" (clouds) because there is nothing in Islamic law to prevent it, and it is a common female name in the Arabian Gulf. Sahab means clouds, its singular is Sahabah, and its plural forms are Suhub and Saha'ib.
