Narrated Ubaid bin Umair:

Once `Umar (bin Al-Khattab) said to the companions of the Prophet (ﷺ) "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."
