Memory, remembrance.
Literally: memory, remembrance
Yaad is remembrance — the memory of the beloved that fills the parted lover's nights, keeping the absent face present in the heart. In separation, yaad is both wound and consolation: it reopens the longing and yet sustains the love across the distance. The ghazal lives much of its life in yaad, the lover companioned only by the recollection of a face he cannot see; in the sacred register, the remembrance (zikr) of the Beloved is the soul's whole occupation.
Yaad in Iqbal’s couplets
Wo bagh ki baharen, wo sab ka chahchahana
Utra tere kinare jab karwan hamara
Khatak si hai jo sine mein gham-e-manzil na ban jae
