Allah has not assigned to any man two hearts within his body

Only that man will busy himself with trivial things who is interested in them. A spiritual traveler who has attained to the stage of greater faith and for whom well doing has become a habit, cannot be fond of anything vain, for no heart can love two contradictory things at one and the same time. 

Allah Himself has said: 

Allah has not assigned to any man two hearts within his body. (Surah al-Ahzab, 33:4)
