A muslim can marry the following except

In Islam, the rules regarding marriage are outlined in the Quran and Hadith. They provide clear guidelines on who a Muslim can and cannot marry. Among the options listed:

• Divorce: A Muslim can marry someone who is divorced. There are specific rules about the waiting period, known as "iddah," for a woman who is divorced or widowed before she can remarry.
• Blood Sister: A Muslim cannot marry his blood sister. It is strictly prohibited, as marrying direct blood relatives is considered incestuous and is not allowed in Islam.
• Friend's Daughter: A Muslim can marry a friend's daughter as long as there is mutual consent and the marriage aligns with the Islamic principles and family agreements.
• Cousin: In Islam, marrying a cousin is allowed. It is quite common in many cultures around the world and is not prohibited by religious laws.

Therefore, among the options provided, a Muslim cannot marry their blood sister due to the prohibition against marrying close blood relatives.
