MUSLIM WIFE INHERITANCE SHARE
The Wife inherits One-fourth (i.e., 1/4) from Husband's property if there are no children or no grandchildren how low soever; otherwise, inherit One-eighth (i.e., 1/8) from the Husband's property as stipulated in the Holy Quran 4:12.
The Wife does not block any legal Islamic heirs from taking an inheritance and vice-versa.
The wife inherits from her Husband only if she is married as per the Islamic ceremony called "Nikah." A wife does not inherit Islamically if she is only married legally, but not Islamically.
A Muslim man's property can be inherited by his wife, children (or grandchildren), and parents (or grandparents) as primary heirs. These are the legal heirs after the death of a married man in Islam. Refer to "Islamic inheritance sharers and residuary" to learn more.
The second wife has the right to the Husband's properties in Islam, and multiple surviving wives are shared equally in Islam as stipulated in the Holy Quran 4:12. Refer to Fixed or Prescribed sharers in Islam for more information.
Wife also can own lifetime gifts (i.e., Hiba) from Husband's property without restrictions.
