Love marriage itself is not haram in Islam — nothing in the Quran or Sunnah forbids two people marrying because they are drawn to each other. What Islam regulates is not the presence of affection, but how the marriage is arranged and conducted. The Quran describes spouses as a source of tranquility, love (mawaddah), and mercy (rahmah) for one another (30:21), and instructs husbands to treat their wives with kindness (4:19) — affection is treated as a purpose of marriage, not a threat to it. The Prophet's ﷺ own marriage to Khadijah (رضي الله عنها) began with her being drawn to his character and sending a trusted friend, Nafisah, to propose to him on her behalf. That account comes from the sirah (Ibn Ishaq), not a hadith, so it carries a different kind of weight — but it still shows that a woman being moved to seek out a particular man for marriage was never seen as improper.
What makes a marriage valid and blessed is the same regardless of whether it began as "love" or "arranged": the woman's free, uncoerced consent — a previously-married woman must be consulted directly, and even a shy virgin's silence counts as her permission (Sahih al-Bukhari 5136, 5137) — her guardian's (wali) involvement, an agreed mahr, witnesses, and a proper nikah contract. What is haram is not love itself, but the mixing and secrecy that sometimes precede it outside those bounds: meeting alone together before marriage, since the Prophet ﷺ warned, "Whenever a man is alone with a woman, Shaytan is the third of them" (Sunan al-Tirmidhi 2165, hasan sahih), or letting attraction substitute for a formal contract instead of leading to one.
So a marriage born from mutual attraction is fully halal, provided it culminates in a proper nikah with consent, wali, mahr, and witnesses, and the courtship leading up to it stays within Islamic bounds — no khalwah (being alone together) or behavior that belongs only after the contract. It is the how, not the presence of love, that Islam legislates.
