Sufism without a doubt especially the Chisti school for its universality and focus on beauty in all its forms.
Hazrat Inayat Khan from that lineage composed this prayer, Salat, which goes, in part (emphasis mine showing its universality)
Salat
Most gracious Sovereign,
Messenger, Messiah, and Savior of humanity,
We greet Thee with all humility.
Thou art the First Cause and the Last Effect,
the Divine Light and the Spirit of Guidance,
Alpha and Omega.
Thy Light is in all forms,
Thy Love in all beings:
in a loving mother, in a kind father, in an innocent child,
in a helpful friend, in an inspiring teacher.
Allow us to recognize Thee in all Thy holy names and forms:
as Rama, as Krishna, as Shiva, as Buddha.
Let us know Thee as Abraham, as Solomon, as Zarathushtra, as Moses, as Jesus, as Muhammad¹,
and in many other names and forms, known and unknown to the world.
