It is forbidden upon you to marry your mothers, your daughters, your sisters, your father’s sisters as well as your mother’s sisters, your brother’s daughters and your sister’s daughters, your mothers who breastfed you and sisters from the breastfeeding side, your wife’s mothers and your stepdaughters who are under your guardianship born for your wives with whom you have made mating; if you have not made mating, you can marry their daughters avoiding their mother, and the wives of your sons proceeded from your loins, and to keep in wedlock two sisters at a time except what happened previously, indeed Lord Allah is the Oft-Forgiving, Merciful.
Here mentioned mother includes, mother, stepmother, father’s mother, and mother’s mother. Granddaughters are also included in the list of daughters. Sisters born in other wives include the sisters in the same parent side, sisters from the same father, sisters in the mother’s or father’s side. It is prohibited for a man to marry the foster mothers, for women the foster mother’s husband, and prohibited to marry their children since foster mothers who breastfed become a mother and her husband become a father and both their children siblings. Lord taught through His Messenger that whatever is prohibited by the blood relation is prohibited in the breastfeeding relationship. It is prohibited to marry the daughter of a woman to her husband, whether the daughter is staying with the mother or not. It is because Lord taught through His Messenger that anyone who has seen a woman’s vagina, then both her mother and daughter are prohibited to him for marriage.
Since it is prohibited to marry the blood-related son’s wives, we can understand that there is no prohibition for marrying the widows of adopted sons or their divorced women. But in the ignorant period, it was prohibited to marry both widow and divorced woman of an adopted son and was permitted the widows of their sons. To annihilate this odious custom Lord made the marriage of Messenger’s adopted son Zaid with Zainaba who was Messenger's cousin. Then Lord commanded Zaid to divorce her and commanded Messenger to marry her giving dowry. It is told in verses 33: 4-5: “Lord has not made your adopted sons as your sons”.
It is told in the case of Zaid and Zainaba in verses 33: 36-40: “It is not suitable for a believing man or a believing woman to have an option in their affairs when a matter has been decided by Lord and His Messenger, and whoever disobeys the Lord and His Messenger, indeed he is strayed into a clear wrong path”. Grandson’s wives are considered like the son’s wives and so it is prohibited for grandfather to marry them.
Today, the Arabic Quran reading Fujjar by rejecting Adhikr are bearing Lord’s Book as the burden carrying donkeys as told in verse 62: 5. They are unaware of the dos and don'ts of the Lord's Book. Hypocrites are perverting the Mercy Adhikr into disbelief and are making permissible the house of worthless Hell for their followers as told in verses 14: 28-29. These Fujjar are fulfilling sexual pleasures with those whom Lord has prohibited. These Mujirims who don’t utilize their intelligence are serving Satan and are following in his footsteps. These worst creatures will be killed by other people belonging to Messenger's community after the second coming of Jesus as explained in verses 4: 91 and 9: 5. At that time only they will admit that not the Arabic Quran, but Adhikr was the Lord's Book as told in verses 38: 8. See explanation 2: 168-169; 6: 26, 89-90 and 9: 67-68.
