No, it is not halal (permissible) to marry your nephew in Islam.
Islamic law prohibits marriage between certain relatives, and a nephew is included in these prohibited degrees of kinship. This is based on Quranic verses and established Islamic legal rulings.
Here's a breakdown of the prohibited relationships:
Prohibited Degrees of Kinship in Marriage (According to Islam)
Islamic law strictly prohibits marriage between close relatives. The following relationships are among those forbidden for marriage:
- Ascendants: Mother, Grandmother (both paternal and maternal), and further up the lineage.
- Descendants: Daughter, Granddaughter (both son's and daughter's), and further down the lineage.
- Siblings: Sister (both full, half-sister from the same father, or half-sister from the same mother).
- Aunts and Uncles: Aunt (father's sister), Aunt (mother's sister), Great-Aunts; Uncle (father's brother), Uncle (mother's brother), Great-Uncles.
- Nieces and Nephews: Niece (sister's daughter), Niece (brother's daughter), Great-Nieces; Nephew (sister's son), Nephew (brother's son), Great-Nephews.
- Affinity (Marriage-based relationships): Mother-in-law, Step-daughter (if the marriage with her mother has been consummated).
Therefore, marrying a nephew, whether he is the son of your brother or the son of your sister, is strictly prohibited in Islam. These prohibitions are based on clear injunctions in Islamic texts and are universally accepted within Islamic jurisprudence.
