Let me remind you of Mulla Rumi's one she'r about the Qur'an:
MA ZE QUR'AN MAGHZ RA BARDAASHTAIM
ISTAKHAWN PAISH-E SAGAAN ANDAAKHTAIM
[I HAVE TAKEN THE BRAIN OUT OF THE QUR'AN - I HAVE THROWN THE (LEFT-OVER) BONES BEFORE DOGS]
Allama Iqbal had said: Sufism is an alien (Ajami) plant in the soil of Islam.
