Since a person will be together with whom he loves in the hereafter, one should love the people who deserve to go to Paradise so that he will be together with them in Paradise. God forbid, if you love the people who deserve to go to Hell, it is possible that you go to Hell in order to be together with whom you love. – Do not say is it possible? It is. They say love is blind. A person may love someone that Allah does not love. He follows that person and goes to the place where he/she goes because a person is together with whom he loves.
Then, love the people that Allah loves so that you will be together with them in the hereafter. Be careful not to be a victim of wrong love and a person who is overcome by his feelings.In Paradise, it is out of question to be together with a person that one does not like or does not want. Then, those who love will be together with the people whom they loved in Paradise; they will transform their ephemeral happiness in the world to eternal happiness in the hereafter.
Because Paradise is a place of complete happiness. A person who enters Paradise will not come across with even the slightest thing that will overshadow his happiness. On the contrary, he will have all of the things that will make him happy and as he likes them to be; there will be no deprivation.
