Is it permissible for a sister to take half of the house left to her by her husband and children after divorce, knowing that the house was purchased solely with the husband's money, and that the law grants her half of the family's assets as a personal right?

A divorced wife has no right to her husband's property beyond the maintenance allowance. Once her waiting period ('iddah) ends, she has no right to maintenance, housing, or anything else from his property. Any law that grants her half of the husband's property contravenes Islamic Sharia, which mandates seeking judgment solely from Allah's law. A divorced woman has no right to half of her husband's house unless the husband willingly donates it. A Muslim is advised to strive to reside in Muslim countries.
