Tafsir Ibn Kathir -> Surah An-Nisa -> Marrying the Wife of the Father is Prohibited

Allah said,

﴿وَلاَ تَنكِحُواْ مَا نَكَحَ ءَابَاؤُكُمْ مِّنَ النِّسَآءِ﴾

(And marry not women whom your fathers married,) Allah prohibits marrying the women whom the father married, in honor and respect to the fathers, not allowing their children to have sexual relations with their wives after they die. A woman becomes ineligible for the son of her husband as soon as the marriage contract is conducted, and there is a consensus on this ruling. Ibn Jarir recorded that Ibn `Abbas said, "During the time of Jahiliyyah, the people used to prohibit what Allah prohibits (concerning marriage), except marrying the stepmother and taking two sisters as rival wives. Allah sent down,

﴿وَلاَ تَنكِحُواْ مَا نَكَحَ ءَابَاؤُكُمْ مِّنَ النِّسَآءِ﴾

(And marry not women whom your fathers married,) and,

﴿وَأَن تَجْمَعُواْ بَيْنَ الاٍّخْتَيْنِ﴾

(and two sisters in wedlock at the same time) ﴿4:23﴾.'' Similar was reported from `Ata' and Qatadah. Therefore, the practice that the Ayah mentions is prohibited for this Ummah, being disgraced as an awful sin, r

﴿إِنَّهُ كَانَ فَـحِشَةً وَمَقْتاً وَسَآءَ سَبِيلاً﴾

(Indeed it was shameful and Maqtan, and an evil way.) Allah said in other Ayat,

﴿وَلاَ تَقْرَبُواْ الْفَوَحِشَ مَا ظَهَرَ مِنْهَا وَمَا بَطَنَ﴾

(Come not near to Al-Fawahish (shameful acts) whether committed openly or secretly) ﴿6:151﴾, and,

﴿وَلاَ تَقْرَبُواْ الزِّنَى إِنَّهُ كَانَ فَاحِشَةً وَسَآءَ سَبِيلاً ﴾

(And come not near to unlawful sex. Verily, it is a Fahishah and an evil way.) ﴿17:32﴾ In this Ayah (4:22), Allah added,

﴿وَمَقْتاً﴾

(and Maqtan), meaning, offensive. It is a sin itself and causes the son to hate his father after he marries his wife. It is usual that whoever marries a woman dislikes those who married her before him. This is one reason why the Mothers of the Faithful were not allowed for anyone in marriage after the Messenger . They are indeed the Mothers of the Faithful since they married the Messenger , who is like the father to the believers. Rather, the Prophet's right is far greater than the right of a father, and his love comes before each person loving himself, may Allah's peace and blessings be on him. `Ata' bin Abi Rabah said that the Ayah,

﴿وَمَقْتاً﴾

(and Maqtan), means, Allah will hate him,

﴿وَسَآءَ سَبِيلاً﴾

(and an evil way), for those who take this way. Therefore, those who commit this practice will have committed an act of reversion from the religion and deserve capital punishment and confiscation of their property, which will be given to the Muslim Treasury. Imam Ahmad and the collectors of Sunan recorded that Al-Bara' bin `Azib said that his uncle Abu Burdah was sent by the Messenger of Allah to a man who married his stepmother to execute him and confiscate his money.

﴿حُرِّمَتْ عَلَيْكُمْ أُمَّهَـتُكُمْ وَبَنَـتُكُمْ وَأَخَوَتُكُمْ وَعَمَّـتُكُمْ وَخَـلَـتُكُمْ وَبَنَاتُ الاٌّخِ وَبَنَاتُ الاٍّخْتِ وَأُمَّهَـتُكُمُ الْلاَّتِى أَرْضَعْنَكُمْ وَأَخَوَتُكُم مِّنَ الرَّضَاعَةِ وَأُمَّهَـتُ نِسَآئِكُمْ وَرَبَائِبُكُمُ اللَّـتِى فِى حُجُورِكُمْ مِّن نِّسَآئِكُمُ اللَّـتِى دَخَلْتُمْ بِهِنَّ فَإِن لَّمْ تَكُونُواْ دَخَلْتُمْ بِهِنَّ فَلاَ جُنَاحَ عَلَيْكُمْ وَحَلَـئِلُ أَبْنَآئِكُمُ الَّذِينَ مِنْ أَصْلَـبِكُمْ وَأَن تَجْمَعُواْ بَيْنَ الاٍّخْتَيْنِ إَلاَّ مَا قَدْ سَلَفَ إِنَّ اللَّهَ كَانَ غَفُوراً رَّحِيماً ﴾

(23. Forbidden to you (for marriage) are: your mothers, your daughters, your sisters, your father's sisters, your mother's sisters, your brother's daughters, your sister's daughters, your foster mothers who suckled you, your foster milk suckling sisters, your wives' mothers, your stepdaughters under your guardianship, born of your wives unto whom you have gone in -- but there is no sin on you if you have not gone in unto them (to marry their daughters), -- the wives of your sons who (spring) from your own loins, and two sisters in wedlock at the same time, except for what has already passed; verily, Allah is Oft- Forgiving, Most Merciful.)
