Determining compatibility between spouses by matching their names and dates of birth

Q: I'm a 22 year old female and I have a friend who believes in hisaab. He wants to get married but he went to the imam to ask him whether he is compatible with the girl. So the imam asked for her name and date of birth to determine compatibility and whether she would be a good wife; how she will be with him and his family. He also predicted that my friend would most likely remain unmarried because he won't find anyone compatible to him. And my friend doesn't know how he used names and date of birth to determine compatibility because the imam went into a different room.

I told my friend that this is haraam in our religion because only Allah knows our future and this is no different than going to a fortune teller or believing in astrology and horoscopes and it's clearly mentioned in Islam that this is haraam because it's associating with Allah, but he doesn't believe me. I'm very worried for him and I would like to know from a knowledgeable person if this is allowed in Islam.
