‘Abd al-Wahid ibn Zayd [known as Abu ‘Ubayda al-Basri] said:
I stopped one time in a valley, where I was startled by a monk who had confined himself in a cell. I said, "Is this a demon, or a man?"
Weeping, the man said, "What is there to fear, other than God? A man degraded by sin, who flees to his Lord, in flight from his own sins—this man's no demon, but a mortal in distress."
"How long have you been here?" I asked. "Twenty-four years," he said.
"Who do you have for company?" I asked. "Wild animals," he said.
"What do you eat?" I asked. "Fruits and vegetation of the earth," he said.
"And you don't miss the company of other people?" I asked. "That's just what I'm fleeing," he said.
"Do you follow Islam?" I asked. He said: "[Submission] is all I know."
Abu ‘Ubayd (sic) said: By God, I envied him his place!
I asked a monk about the iron pole he had [tied himself to?]: "What's the hardest thing about being out here by yourself?" "There's nothing hard about it," he said. "Solitude is sociability, for the seeker."
