There was a talk between Imam Sadiq (as) and Abi Haroun, the sightless.
Here is the conversation.
The Imam (as) said: “O aba Haroun! Allah, the Almighty, does not want a betrayer to accompany him.”
Abu Haroun went on saying: “Who is betrayer?”
The Imam (as) replied: “One who deprives a Dirham from a believer or keep him away from something in the worldly life.”
Then he continued: “I appeal to Allah from His anger.”
Afterwards, he added: “Allah, the Almighty, does not want the following three groups to enter His paradise: One who is against the Lord; one who is against an Imam of Guidance; or one who limits a right of a believer.”
Abu Haroun said: “Does he have to give from what he owns and from his superiority?”
The Imam (as) replied: “He has to give from himself and his soul; and if a believer becomes stingy, if he does not do so, but he is considered to obey Satan.”
