What is the meaning of the name "Rodina," and is it permissible to name a daughter with it? And does it mean a sword among the swords of the Prophet, peace and blessings be upon him, attributed to a woman named "Rodina" who used to make swords?

Al-Rudayni is a spear, not a sword, named after a woman in pre-Islamic times called Rudaynah who used to fashion spears. If the intention is to name "Al-Rudayni," its meaning has not been clarified in Arabic, and it may be foreign. It is advised to avoid it unless its meaning is known and does not contain anything bad. However, if the intention is to name "Rudaynah," there is no legal impediment, as the default rule for names is permissibility unless they contain something forbidden.
