The wife who usurped this money has to offer Tawbah (repentance to Allah, Exalted be He) and pay it back to the inheritors of her husband especially to her step-daughter. The woman who insinuated to her has to pay back what she took, and she, along with anybody who knew and did not disapprove the guilty action, has to repent to Allah (Glorified and Exalted be He).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
