Hujjat
Yes, the word appears in Surah Al-An'am 6:149 referring to Allah's conclusive argument (al-hujjat al-balighah).
Traditionally Hujjat is masculine, though the abstract concept is gender-neutral in Arabic grammar.
It was historically favored by scholarly families in theological centers like Qom and Mashhad, symbolizing intellectual authority.
It is extremely rare in modern usage, with fewer than 1 in 100,000 births in Persian-speaking regions.
The term 'Hujjat' has special significance in Shia theology regarding the proof of God's existence and the Imamate, though the name is used broadly by all Muslims.
