And Allah has said (in Surah An-Nisa) «وإن خفتم شقاق بينهما فابعثوا حكما من أهله وحكما من أهلها» "If you fear dissension between the two (husband and wife), appoint an arbitrator from his people and an arbitrator from her people." (to the end of the verse).
Narrated Al-Miswar bin Makhrama Az-Zuhri: I heard the Prophet saying, "Banu Al-Mughira have asked my leave to let `Ali marry their daughter, but I give no leave to this effect."
