In India some Muslim people goto a person and inquire whether their marriage will work out properly or not. Its called Faal Nikalna (somewhat similar to astrology).
Does this practice have any legitimacy in Islam ???
[He is] Knower of the unseen, and He does not disclose His [knowledge of the] unseen to anyone -- Qur'an 72:26
Instead, Muslims ask Allah for guidance through istikhara:
Salat al-Istikharah is a prayer recited by Muslims when in need of guidance on an issue in their life.
