What is the ruling on one who swore to his wife, saying, "Upon me be the unlawful (haram) that I will not take money from you," while angry, and then took money from her, forgetting his oath? And does separation occur between them? If it does occur, when does her waiting period (iddah) begin? And is his wife considered forbidden to him if a period exceeding three months passes without knowledge of the ruling?

The early and later generations of scholars differed concerning one who swears by deeming something unlawful. The preponderant opinion is that this is an oath that does not necessitate divorce, even if the swearer intended it. Consequently, the swearer is only required to offer expiation for an oath if he breaks it, and his wife remains under his marital bond. One should be cautious of words of prohibition and divorce due to their serious impact on the marital relationship.
