Meaning
Old, ancient, time-worn.
How Iqbal uses it
Iqbal speaks of asar-e-kuhan, an ancient trace or effect, mourning that the time-old fire of true passion no longer animates either the storyteller's words or the candle's slow melting.
See it in the verse
Kuhan in Iqbal’s couplets
Aaeen-e-naw se darna, tarz-e-kuhan pe arna
Manzil yahi kathin hai qaumon ki zindagi mein
Manzil yahi kathin hai qaumon ki zindagi mein
To fear the new order, and to dig in stubbornly on the old way — this is the hardest pass in the life of a people.

Sultani-e-jamhur ka aata hai zamana
Jo naqsh-e-kuhan tum ko nazar aae miTa do
Jo naqsh-e-kuhan tum ko nazar aae miTa do
The age of the people's rule is arriving; whatever old patterns you still see, wipe them away.
