However, if this union (between male and female) occurs through disobedience (fornication) then the resulting child is not considered a part of a person’s true lineage. That is why a daughter born from adultery is not mentioned in Allah’s saying, ‘Prohibited to you (for marriage) are: your mothers and daughters’ (Surah 4:23) because she is not considered a daughter according to the most authentic teaching of our (Islamic) scholars and the most authentic teaching of our religion. If there is no legal lineage then there is no legal relationship; for adultery does not prohibit (from marriage) the daughter of the mother (you committed adultery with) nor the mother of a woman (you committed adultery with). What is lawfully prohibited is not also prohibited due to sin, for Allah has bestowed lineage and relation through marriage upon His servants and greatly esteemed these relationships. Allah has also established laws identifying what is legal and what is prohibited, which are not equal to each other; therefore falsehood cannot be a part of these laws." I (Qurtubi) said: The scholars have differed on the permissibility of a man marrying his daughter who was the result of an adulterous relationship; or for that matter marrying his sister or granddaughter who was the result of adultery. Some prohibited this type of relationship; among them was Ibn Al Qasim, which is also the saying of Abu Hanifa and his companions. Others however, allowed this type of marriage such as Abdul Malik Al Maj’shun, which is also the saying of Al Shafi’i.
