Meaning
The body.
How Iqbal uses it
Tan, paired with man (the heart/mind), frames Iqbal's body-and-soul dualities; the body is the dust that must be animated by spirit and striving.
See it in the verse
Tan in Iqbal’s couplets
Pani pani kar gai mujh ko qalandar ki ye baat
Tu jhuka jab ghair ke aage na man tera na tan
Tu jhuka jab ghair ke aage na man tera na tan
The wandering sage's words washed over me with shame: the moment you bow before another, neither your mind nor your body is your own.

Man ki daulat hath aati hai to phir jati nahin
Tan ki daulat chhanw hai aata hai dhan jata hai dhan
Tan ki daulat chhanw hai aata hai dhan jata hai dhan
The wealth of the inner self, once gained, never leaves you again; the wealth of the body is mere shade, money comes and money goes.
