Once, Imam Kadhim (a.s.) was passing by the house of Bishr Haafi, when he heard the sound of dance and music coming from inside.
At that very moment a slave-girl came out of the house to throw some garbage.
“Is the owner of this house a free person or a slave?” the Imam (a.s.) asked her.
The slave-girl replied, “He is a free man.”
Hearing this, the Imam (a.s.) remarked, “You speak the truth, for had he been a slave, he would have feared his Master.”
When the slave-girl came back inside the house, Bishr, who had been consuming wine, asked her what took her so long. As soon as the slave-girl related what had happened, Bishr immediately got up and ran bare-footed after the Imam (a.s.). Once he had caught up with the Imam, he expressed shame and repentance over his acts, sought forgiveness and amended his wrongful ways( Darsi Az Akhlaaq, pg. 128; Minhaaj al-Karaamah (of A’llamah Hilli).)
