Yes, simply loving your cousin is halal (permissible) in Islam.
The permissibility stems from the fact that cousins are mahrams in terms of marriage eligibility until a marriage contract is actually established. Liking or even loving them, in and of itself, doesn't violate any Islamic principles. However, the crucial point is to avoid any haram actions arising from that affection, such as:
- Illicit Relationship: Engaging in pre-marital relations, physical contact, or private meetings (khalwa) is strictly forbidden.
- Forgetting Islamic Boundaries: Crossing the boundaries of modesty and respect as outlined in Islamic teachings.
- Ignoring Religious Obligations: Allowing the emotions to distract from fulfilling religious duties.
Therefore, while love itself isn't forbidden, how you act upon it matters significantly. If the intention is marriage and you follow the correct Islamic procedure (involving guardians, etc.), then pursuing the relationship is permissible. However, if marriage is not possible or intended, the love must be managed within the constraints of Islamic guidelines, meaning no inappropriate behavior or contact.
It's also important to note that while religiously permissible, there can be societal or familial considerations that may need to be addressed depending on specific cultural norms. Furthermore, the reference points out potential medical concerns, so genetic counseling may be advisable if marriage between cousins is being considered.
