Once, Imam Sadiq (a.s) related: “There was a piece of land that I owned in partnership with an astrologer and it was mutually decided that it should be divided between us. He made preparations so that his arrival should be in an auspicious hour while I should arrive in an inauspicious hour so that the better portion of the land fell in his hands. The land was divided but it so happened that the better portion came as my share of the land! The man slapped his right hand over his left in regret and said ruefully: “Oh! Had I never lived to see such a day!”
I said to him: “Why are you so upset today?” He said: “I am an astrologer and I brought you out of your house in an inauspicious hour while I myself came out in an auspicious hour. However, now that the land has been divided, you have come to acquire the better portion of it.”
I (the Imam) said: “I shall inform you of a tradition of the Noble Prophet (s.a.w) wherein he said: ‘If one desires that Allah wards away from him the inauspiciousness of a day, he should start his day by giving charity, and if one desires to ward away the inauspiciousness of the night, he should commence his night by giving charity.’”
The Imam (a.s) then said (to the astrologer): “I gave charity while coming out (of my house) today; charity is better for you than astrology.”( Ba Mardum In Guneh Barkhord Konim, pg. 135; al-Kafi, vol. 4, pg. 6 )
