Intersect marriage is not a commonly used term, and it is unclear what it refers to. However, there are two related terms that may be relevant: interfaith marriage and intermarriage between different Muslim sects.

• Interfaith marriage: This refers to marriage between spouses who profess different religions. Although interfaith marriages are often established as civil marriages, in some instances, they may be established as a religious marriage, depending on the religious doctrine of each of the two parties religions. Some religions prohibit interfaith marriage, while others allow it with requirements for ceremony and custom.

• Intermarriage between different Muslim sects: This refers to marriage between individuals from different sects of Islam, such as Shia and Sunni. The ruling regarding intermarriage between Shia and Sunni is a topic that many in the Muslim society avoid shedding light on.

It is important to note that marriage, whether interfaith or between different Muslim sects, can be a complex issue with various cultural, religious, and legal considerations. In some cases, consent of the guardian may be required, especially in the case of a young woman who has no experience.
