Rulings when both husbands claim to have contracted the marriage first without proof.
General Chapter
Al-Mughni
Book of Marriage
Primary text
If both claim to be the preceding contractor without proof, neither claim is accepted. If the woman confirms one of them, her admission is not accepted, as the opposing husband is the claimant whose right is affected by her admission, similar to her admitting a divorce against him. If the husbands claim the woman knew which contract was prior and she denies it, she is not required to swear an oath to that effect.

If separation occurs between her and one husband due to her choice or the drawing of lots in favor of the other, and she then admits to the favored one that his contract was prior, her admission should be accepted as there is no opposing claimant. If the two contracts occurred simultaneously, both are void from the beginning, and there is no dower, inheritance, or mutual inheritance between them. If the simultaneity is unknown, the marriages are annulled. If one husband enters into the marriage, some narrations from Ahmad suggest half the dower is due, determined by lot, as one contract is valid but was dissolved before consummation.
