Hadith 646
۞
If a man dies and leaves behind a wife and a son, the wife receives one-eighth of the inheritance, and the remainder goes to the son. Similarly, if he leaves behind a wife and a daughter, the wife receives one-eighth, and the remainder goes to the daughter.
If he leaves behind a wife, a son, and a daughter, or multiple sons and daughters, the wife receives one-eighth, and the remainder is divided among the sons and daughters, with the male receiving the share of two females.
إِذَا مَاتَ الرَّجُلُ وَ تَرَكَ امْرَأَةً وَ ابْناً فَلِلْمَرْأَةِ الثُّمُنُ وَ مَا بَقِيَ فَلِلِابْنِ وَ كَذَلِكَ إِنْ تَرَكَ امْرَأَةً وَ ابْنَةً فَلِلْمَرْأَةِ الثُّمُنُ وَ مَا بَقِيَ فَلِلِابْنَةِ فَإِنْ تَرَكَ امْرَأَةً وَ ابْناً وَ ابْنَةً أَوْ بَنِينَ وَ بَنَاتٍ فَلِلْمَرْأَةِ الثُّمُنُ وَ مَا بَقِيَ فَلِلْبَنِينَ وَ الْبَنَاتِ لِلذَّكَرِ مِثْلُ حَظِّ الْأُنْثَيَيْنِ.
