This honorable Ayah is the Ayah that establishes the degrees of women relatives
who are never eligible for one to marry, because of blood relations, relations established
by suckling or marriage. Ibn Abi Hatim recorded that Ibn `Abbas said, "(Allah said)
I have prohibited for you seven types of relatives by blood and seven by marriage.''
Ibn `Abbas then recited the Ayah,
﴿حُرِّمَتْ عَلَيْكُمْ أُمَّهَـتُكُمْ
وَبَنَـتُكُمْ وَأَخَوَتُكُمْ﴾
(Forbidden to you (for marriage) are: your mothers, your daughters, your sisters...)
At-Tabari recorded that Ibn `Abbas said, "Seven degrees of blood relation and seven
degrees of marriage relation are prohibited (for marriage).'' He then recited the
Ayah,
﴿حُرِّمَتْ عَلَيْكُمْ أُمَّهَـتُكُمْ
وَبَنَـتُكُمْ وَأَخَوَتُكُمْ وَعَمَّـتُكُمْ وَخَـلَـتُكُمْ وَبَنَاتُ الاٌّخِ وَبَنَاتُ
الاٍّخْتِ﴾
(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) and these are the types prohibited by blood relation.'' Allah's statement,
﴿وَأُمَّهَـتُكُمُ الْلاَّتِى أَرْضَعْنَكُمْ
وَأَخَوَتُكُم مِّنَ الرَّضَاعَةِ﴾
(Your foster mothers who suckled you, your foster milk suckling sisters) means,
just as your mother who bore you is prohibited for you in marriage, so is your mother
from suckling prohibited for you. Al-Bukhari and Muslim recorded that `A'ishah,
the Mother of the Faithful, said that the Messenger of Allah said,
«إِنَّ الرَّضَاعَةَ تُحَرِّمُ مَا
تُحَرِّمُ الْوِلَادَة»
(Suckling prohibits what birth prohibits.) In another narration reported by Muslim,
«يَحْرُمُ مِنَ الرَّضَاعَةِ مَا يَحْرُمُ
مِنَ النَّسَب»
(Suckling establishes prohibited degrees just as blood does.)
