Volume 6, Book 60, Number 62:
Narrated Ubaid bin Umair: Once ‘Umar (bin Al-Khattab) said to the companions of the Prophet
“What do you think about this Verse:–“Does any of you wish that he should have a garden?” They
replied, “Allah knows best.” ‘Umar became angry and said, “Either say that you know or say that you
do not know!” On that Ibn Abbas said, “O chief of the believers! I have something in my mind to say
about it.” Umar said, “O son of my brother! Say, and do not under estimate yourself.” Ibn Abbas said,
“This Verse has been set up as an example for deeds.” Umar said, “What kind of deeds?” Ibn Abbas
said, “For deeds.” Umar said, “This is an example for a rich man who does goods out of obedience of
Allah and then Allah sends him Satan whereupon he commits sins till all his good deeds are lost.”
