Meaning
The sound, untainted heart; the pure heart that alone avails before God.
Literally: the sound heart
How Iqbal uses it
Qalb-e-saleem, the sound and undivided heart of the Quran, is the spiritual organ Iqbal sets above cold intellect. It is the seat of intuition, love and certitude, the heart through which the self truly knows.
See it in the verse
Qalb-e-Saleem in Iqbal’s couplets
Gesu-e-tabdar ko aur bhi tabdar kar
Hosh-o-khirad shikar kar qalb-o-nazar shikar kar
Hosh-o-khirad shikar kar qalb-o-nazar shikar kar
Make the radiant tresses more radiant still — capture sense and reason, hunt down the heart and the eye.

Qalb o nazar ki zindagi dasht mein subh ka samaan
Chashma-e-aftab se nuur ki naddiyan ravaan
Chashma-e-aftab se nuur ki naddiyan ravaan
The life of the heart and the eye is like daybreak in the desert; from the spring of the sun, rivers of light flow out.
Awakening · Hope · Self-Knowledge
