Renowned Muslim philosopher and Sufi mystic Ibn al-Arabi rahimahu Llah had this to say about inter-faith harmony:

O Marvel,
a garden among the flames!
My heart can take on
any form:
a meadow for gazelles,
a cloister for monks,
For the idols, sacred ground,
Kaaba for the circling pilgrim,
the tables of the Torah,
the scrolls of the Quran.
I profess the religion of love;
wherever its caravan turns along the way,
that is the belief,
the faith I keep.
