Dhikr and Fikr
These are all a wayfarer’s search posts about whom the Quran says: He taught all the names.
The achievements of Rumi and ‘Attar are stations of dhikr; the computations of Bu ‘Ali Sina pertain to the station of fikr.
To measure time and space is the station of fikr, to recite: Exalted be my Lord, Most High is the station of dhikr.
