I want to know the answer to the following question:
What modern country did Ibn Sina travel to after the end of the Samanid dynasty?
All the background I'm provided with is that "Ibn Sina seems to have declined the offers of Mahmud of Ghazni, and proceeded westwards to Urgench in modern Turkmenistan, where the vizier, regarded as a friend of scholars, gave him a small monthly stipend.". Is that enough to answer the question?
