What is the ruling on naming a newborn girl "Saydal"?

Names in Islam are important due to their effect on the named person, and the Prophet, peace and blessings be upon him, changed many names for the better. Children should not be given foreign names with unknown meanings, lest they contradict Islam. The aforementioned name has no origin in Arabic dictionaries like "Sattar Al-Kaaba," and the segment "cidal" means "killer" in English. Therefore, it is advisable to avoid this name and choose a name from among the names of the female Companions.
