Iqbal identifies intuition (often linked to the Qur'ānic–Sufi idea of the qalb, or "heart") as an immediate, direct mode of knowing Ultimate Reality (God), not mediated by discursive reasoning $\Rightarrow$ this supports (A)
. He insists that genuine spiritual insight is not mere private feeling; it has an objective purchase on reality when disciplined and tested in life and history $\Rightarrow$ this supports (B)
. Iqbal consistently locates this faculty in the "heart" as a dynamic center of selfhood that synthesizes love, will, and knowledge, over and above the calculative intellect $\Rightarrow$ this supports (C)
. Option (D) is rejected because Iqbal treats the intellect/mind as necessary but insufficient for grasping the Absolute; intuition is not a mere property of discursive intellect
. \[ \boxed{\text{Hence, (A), (B), and (C) are correct; (D) is not.}} \]
