"It is hurtful and really it is for no reason," Imam Ahmed Shqeirat said.
"We are a center of peace and worship for all."
The open house came a week after a valley mosque was targeted by an Islamophobic attack when a small group of racists gathered outside the mosque.
Led by Dean Saxon, a well-known street preacher, racists tore up pages of the holy Quran and spat on it.
"It is free speech, whether it incites hate or love it is free," Saxon told in campuses.
The Islamophobic preacher has been rejected by several students with one approaching him and another hitting him with his bike.
Countering Saxon's hate speech, religious leaders from different faiths showed up at the Islamic Center in Tempe last Friday to send a message of peace to the Muslim community.
Despite his failure to draw supporters, the Islamophobic preacher plans to target other mosques in Valley.
