Abu Said's disciples were worried by his behavior.
"When he recites from the Quran, he makes mistakes," said one disciple. "He keeps leaving out verses."
Another remarked, "Perhaps his mind is on other things."
"Or perhaps he is ill," said another.
Finally, they decided to ask Abu Said if something was the matter, and Abu Said just smiled. "Yes, I know I am skipping some verses. They are the verses about God's wrath."
The disciples still looked puzzled, so he explained. "For me, there is only God's mercy; I leave God's wrath to others. His mercy is what I recite."
