Is naming a child "Sayfullah" (Sword of God), "Sayfud-Din" (Sword of the Religion), or "Sayful-Islam" (Sword of Islam) harmful, especially "Sayfullah," which was said to contain an error?

Naming someone "Sayf Allah" (Sword of Allah), "Sayf al-Din" (Sword of thed Religion), or "Sayf al-Islam" (Sword of Islam), or being titled with these names, is permissible and good. Khalid ibn al-Walid was named a sword from the swords of Allah, as stated in the Hadith. Similarly, good titles have been reported for Abu Bakr, Umar, and Hamza.
