لوح بھی تو قلم بھی تو تیرا وجود الکتاب کس کتاب میں ہے؟

The profound verse "لوح بھی تو قلم بھی تو تیرا وجود الکتاب" is a celebrated line from Allama Iqbal's poetic collection. It is specifically featured in بال جبریل (Baal-e-Jibreel), one of his most influential works. The other options are incorrect as this verse is not found in them.
