Omar Ibn Al-Khattab gave safety to the people of Jerusalem after its conquest
The answer is: right
When the Muslims conquered Jerusalem in 634 AD, Caliph Umar ibn al-Khattab gave security to the people of Jerusalem.
And he wrote a covenant for them, pledging their security.
This is to facilitate their lives and encourage them to build and work in Jerusalem.
This was part of the custom that was practical between Muslims and Christians.
Omar Ibn Al-Khattab's kindness and mercy dealt with the people of Jerusalem to open their hearts and welcome him.
He made Jerusalem an open city that welcomes people from different cultures.
And continues until now the age and interest of Muslims in this holy city.
