The inscription of the Dar Al Hijrah mosque reads "IN THE NAME OF GOD: Say: O people of the Book! come to common terms as between us and you: that we worship none but Allah; that we associate no partners with Him; that we erect not from among ourselves Lords and patrons other than Allah. If then they turn back say: Bear witness that we at least are Muslims bowing to Allah's will." - from SperryFiles.com.

There is an agreement between the Muslim property owners and the Masjid administration that whenever there is the need to start the construction of the expansion, the owners will sell their properties and donate the money for the expansion project.
