Such a beautiful story right here!
A man traveled from Mecca to Madinah and then fell asleep whilst in the city of Madinah. When he woke up, he thought his bag had been stolen from him.
He saw Imam Jafar Al-Sadiq, and he seized him by the collar, saying, “You have taken my bag I know it!”
Imam Jafar said, “How much money was in it?” He said, “A thousand Dinars.”
Imam Jafar then took him home and gave him a thousand Dinars from his own wealth.
When the man went back to his place in Mecca, he saw that his bag was there! He apologetically came back to the Imam bringing back the money. However, the Imam did not accept it saying, “We will not take back what we have given.”
The man then asked around saying, “Who is this person?”
They (The People of Madinah) said, “He is Imam Jafar al-Sadiq, May Allah be well pleased with him.”
