What is richest man in afghanistan?

As an AI language model, I cannot provide real time information. However, as of 2021, it is not clear who the richest man in Afghanistan is due to the political instability and economic challenges faced by the country. Prior to the Taliban takeover, some of the known wealthy individuals in Afghanistan were involved in sectors such as construction, telecommunications, and banking. However, with the growing uncertainty, businesses have faced setbacks and it is difficult to determine wealth accumulation in current times.
