I want to know the answer to the following question:
In what year did the Day of Thirst occur?
All the background I'm provided with is that "Following the Umayyad defeat in the "Day of Thirst" in 724, Ashras ibn 'Abd Allah al-Sulami, governor of Khurasan, promised tax relief to those Sogdians who converted to Islam, but went back on his offer when it proved too popular and threatened to reduce tax revenues.". Is that enough to answer the question?
Answer: yes
