You have to prove the accused went there with the intention to kill. He could have gone with the intention to talk about their debt situation, but then saw the victim and went red with rage or something like that.
It's really, really hard to get prove exactly what someone was thinking. You need a very concrete piece of evidence that proves intent, just going somewhere is not going to be enough.
How about going there completely disguised, and pretending to go to a different floor in the building than Fahim? If he went there to talk to him, he wouldn't press a button in the elevator for a different apartment.
