Gharib
Yes. Gharib is an authentic classical Arabic word used historically as a personal name. It is attested in Arabic lexica and literature; the word also appears in Islamic sciences (e.g., hadith terminology) but that usage does not prevent it from being a permissible personal name.
Literally it means 'stranger', 'foreigner' or 'rare/unusual', derived from the Arabic root غ‑ر‑ب which conveys foreignness and rarity.

Yes. It is short, classical and meaningful. Some families may prefer variants or paired names depending on local sensibilities, but Gharib remains a culturally authentic option.
