After glorifying Allah and praising the Holy Prophet (s) let it be known to you, Ibn Abbas, that a man feels very happy if he achieves a thing without understanding that it would have ultimately come to him and he would not have missed it, and sometimes he feels sorry at not acquiring a thing which was not destined for him and which he could never have acquired. Only such things as will earn for you a reward in the next world should please you and you should only feel sorry for losing rewards of the next world. If you attain worldly pomp and pleasures then let not your happiness increase along with every enhancement of such pleasure and if you lose any of these pleasures then do not feel sorry at the loss because you must only feel sorry at the loss of such things as will be of use to you in the next world.
