The residents of al-Khalisa left their homes on 11 May 1948 following the rejection of approaches made by them to the Haganah asking for an "agreement".
 According to Yigal Allon, the commander of Operation Yiftach, the villagers left following his Whispering Campaign.
This involved instructing  the leaders of Jewish villages in the area to warn their neighbours that "a great Jewish reinforcement has arrived in Galilee and that it is going to burn all the villages of the Huleh."
Post-war IDF analysis seems to undermine this claim.
Allon himself writes that the fall of Safad and the success of Operation Matateh were also reasons for the villagers departure.
He describes them as some of "the tens of thousands of sulky Arabs who remained in Galilee."
He also states that "The building of the police station at Halsa (al-Khalisa) fell into our hands without a shot."

The village's residents stated that after they fled, only the local militia remained, but withdrew after shelling from the Jewish town of Manara and after seeing an armored unit approaching al-Khalisa.
 Former villagers, interviewed in Tel al-Zaatar camp in Lebanon in 1973, recounted that when they returned to the village; 
We found that the Jews had burned and destroyed the houses belonging to Ali Zakayan, Abu Ali Muhammad Hamadih, Mustafa al-Haj Yusif, Issa Muhammad, Ali Salih Ahmad, Muhammad Arab al-Haj Mahmud, Salih Ismail, Sari al-Khadir, Dawud Hussein, Abdul-Raziq Hamid, Qassim Muhammead al-Salih and Ali Hussein Mahmud ... The village was in ruins.

According to Walid Khalidi, 1992, "stone rubble from the houses markes the site.
The school and the Mandate government´s office buildings stand abandoned, as does the village mosque and minaret.
The level land surrounding the site is cultivated by settlement of Qirat Shemona, while the mountainous areas are either used as pastures or are wooded."

According to Meron Benvenisti, 2000, "the mosque of al-Khalsa, one of the few structures that remain of that Galilee Arab village, is situated in a municipal park in the older section of the Jewish town of Kiryat Shemona.
It serves as the local museum dedicated to the memory of townspeople who have fallen in Israel's various wars."
