“Islamic law has placed certain restrictions on the choice of your spouse depending upon blood relationships and religious affiliations.” Maulana Sayyid Muhammad Rizvi has summarized these laws in a beautiful way: Restrictions based on Relationship There are certain blood relations which are considered haraam for you as far as marriage is concerned.
(As a general rule, anyone who is your mahram is forbidden to you for marriage.) The list of such relatives is given in the Qur’an as follows: For Man: mother, daughter, paternal aunt, maternal aunt, niece, foster-mother, foster-sister, mother-in-law, step-daughter, daughter-in-law, all married women, sister-in-law (as a 2nd wife) ( See Surah an-Nisaa’ 4:23-24 ) For Woman: father, son, paternal uncle, maternal uncle, nephew, foster-mother’s husband, foster-brother, father-in-law, stepson, son-in-law.
Restrictions based on Religion A Shi’ah Muslim man can marry: a Shi’ah Muslim woman and a non-Shi’ah Muslim woman. However, if there is danger of being misled, then it is haraam . He can also marry a Jewish or Christian woman in mut’a only. But he cannot marry a woman of any other faith. A Shi’ah Muslim woman can marry: a Shi’ah Muslim man or a non-Shi’ah Muslim man, although it is better not to do so; and if there is danger of being misled, then it is haraam .
But she cannot marry a non-Muslim man.[^13] Cousin Marriages Though Shariah does not forbid marriage between first cousins, but there are opinions advocating against them mainly due to a probable risk of the offspring inheriting genetic defects/diseases.
