Often we are pleased with ourselves when we perform a good deed, but the Imam (as) explains the hard part is keeping the reward of that deed.
“Abu Ja’far (as) has said, ‘’Ibqa (preservation) of a deed is more difficult than performing the deed.’ The narrator then asked, ‘What is ‘Ibqa’?’ The Imam said, ‘It is when a man maintains good relations with relatives or spends something just for the sake of Allah, Who has no partners. This will be recorded for him as a good deed, performed secretly. He then mentions it to people, and then it (deed performed secretly) is deleted but is recorded as a good deed performed publicly. Then he mentions it to people again and it then is deleted and is recorded as a deed to show off.’”
Sanad: A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Asbat from certain individuals of his people from abu Ja’far (as) above
