One day Haroun Rashid gave the order to give Bahlool a reward. When it was given, Bahlool didn't take it and returned it. He said, “Give this money to the people whom you took it from. If you don't return it to their owners, then there will certainly come a day when the Khalifa will be demanded to repay his debt. That day the Khalifa will be empty-handed, and, besides being shameful and regretful, there will be nothing.”
Haroun Rashid trembled from listening to Bahlool, started crying, and affirmed Bahlool's statement.
