Marw Rud
An excerpt from the Safar-nama of Nasir Khusraw:
“Afterwards I went to Shuburghan and spent the night in a village in Faryab. From there I went via Samangan and Talaqan to Marw Rud and thence to Merv. Taking leave from my job, I announced that I was setting out for the pilgrimage to Mecca. I settled what debts I owed and renounced everything worldly, except for a few necessities.”
