Impermissibility of favoring any of the sons as regards inheritance

Q: Our maternal grandfather died leaving our mother Munirah bint `Ali, her sister Latifah and our maternal grandmother Nurah. Our mother Munirah died after the death of her father. Her mother Nurah died after her. Are Munirah's children entitled to receive the share of their mother's inheritance from her father or not?

A: If the matter is exactly as what is mentioned in the question, Munirah's heirs inherit her estate after implementing her Shar`y (Islamic legal) will, and paying back her debts. Such estate includes Munirah's share of her father's inheritance. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
