Dawud al-Ta’i passed along the lane of ‘Amr b. Hurayth, where there were baskets full of ripe dates in even rows. On seeing them, his soul began to crave them. "Let's go," he said to his soul, and went to the vendor and said, "Give us one dirham's worth." "And where's the dirham?" the vendor said. "I'll give it to you tomorrow," Dawud said. "Go on about your business," the vendor said.
A man [in the crowd] spotted Dawud and said to the vendor, "What did that man say to you?" The vendor said, "He said: 'Give me one dirham's worth of dates.'" At this, the man held out a sack holding one hundred dirhams, and told him, "Here. If he accepts one dirham's worth of dates from you, you can keep the rest."
When the vendor caught up to Dawud, he was berating his soul, saying: "You, who are not worth one dirham in this world, you wish for Paradise?" The vendor said to him, "Come back, and take as much you need."
"Get away from me," Dawud said, "I was just testing myself.”

Sufyan al-Thawri passed along the lane of ‘Amr b. Hurayth, together with a man who gawked left and right at all the fruit on display. When they arrived at the gate of Musa ibn Talha [in the neighborhood of the Kunasa, which was Kufa's refuse depot], the man stepped in human excrement. Sufyan said to him: "Everything you were gawking at turns into this."
