The members have given good advice in this thread, and I would like to mention one more thing:
As Insaan, we, generally, are very hasty. Sometimes we make Du`aa for things without knowing that what we are asking for is actually bad for us. Sometimes we may wish for something but regret it later. Say you had a friend, for example. You are close with this friend. However, one day, this friend does something which causes you to become very upset. Maybe he stole some money from you, for example, or stole a job you wanted for yourself, or, there was this woman you wanted to marry, but instead he went and married her first. All of these are things that, when it happens, you might become quite angry at this person, despite him being your friend, and when Insaan gets angry, generally, he loses his senses. He doesn't think straight. It is said that anger starts off with madness and ends off with regret, because in your state of extreme anger, you will say and do many things which you will come to regret later in life. So, for example, someone had done something to wrong you, and now you're in a terrible mood about it, very angry, seeing red, and suddenly you make Bad-Du`aa against this person. You curse them. This friend of yours, for example. The one who stole that money from you, or that girl you wanted to marry. Now you curse him. But, what if it really gets answered? Let's say, hypothetically, it really does get answered and that person drops down dead. The thing is, that person was your friend, and so now, after your anger has passed, and you realise that your friend is dead because of you, you will suffer a great deal of regret, because you'll realise that it wasn't worth it. Your friend was worth more than the thing you became angry at him about. You'll regret having made that curse, but, alas, it is too late! The curse has already been said.
Never do things in a state of anger. Anger clouds your mind, clouds your judgement, and causes you to make mistakes. Never make a decision while angry. This is why, when studying Iftaa the person learns that a Mufti must not ever give a Fatwaa while angry, and a Qaadhi (Judge in an Islaamic court) must never give a judgement while angry. They must wait until the anger has abated, and their mind is clear, and thereafter they will give the Fatwaa or the judgement.
So the question now is, what has this person done to you, that you would want him to drop down dead? Also, what connection does this person have with you? Is he a friend? Family member?
There is one more thing to remember. There is a Hadeeth narrated in Sunan at-Tirmidhee:
أحبب حبيبك هوناً ما عسى أن يكون بغيضك يوماً ما, وأبغض بغيضك هوناً ما عسى أن يكون حبيبك يوماً ما
Ahbib Habeebaka Hownam Maa, `Asaa ay Yakoona Bagheedhaka Yowmam Maa, wa Ab-gidh Bagheedhaka Hownam Maa, `Asaa ay Yakoona Habeebaka Yowmam maa...
"Love your friend to a degree; he may become your enemy one day. Hate your enemy to a degree; he may become your friend one day."
According to some of the Muhadditheen, this is reported from Rasoolullaah صلى الله عليه وسلم
. According to the majority of the Muhadditheen, though, like Imaam ad-Daaraqutnee, Imaam adh-Dhahabi, Imaam al-Bayhaqi, and others, it was not Rasoolullaah صلى الله عليه وسلم
who said this, but rather, it was Hadhrat `Ali ibn Abi Taalib رضي الله عنه
In any case, what the Hadeeth teaches us is to never go overboard, whether it be in loving a person or hating them. We are only extreme in our love for Allaah Ta`aalaa.
