Kholoud
The exact proper name Kholoud does not appear as a personal name in the Qur'an; however the root relating to eternity (kh-l-d) is used in Qur'anic descriptions of everlasting reward and abode.
Yes. Because it is a semantically transparent Arabic word, Kholoud is found in various Muslim communities, including East African Arabs and families influenced by Arabic naming practices.
Both names share the semantic field of perpetuity. Kholoud (خلود) is a noun meaning 'eternity', while Khalida (خالدة) is an adjective meaning 'eternal' or 'everlasting'.
Nicknames vary by language and community; common diminutives include Khul or Lood in colloquial speech, but many families prefer the full form due to its formal tone.
Kholoud is classical in origin (from Arabic lexicon) and has been used historically; in contemporary times it remains uncommon, lending it a rarer, distinguished quality.
