Which hadith is related to love? Thank you, and may Allah reward you with the best.

If the intention is a Prophetic Hadith about love, then the Hadith: "Whoever loves passionately, keeps it secret, remains chaste, and dies, is a martyr" has a weak chain of narration, but its meaning is sound. And the Hadith: "Nothing is seen for two who love one another like marriage" is authentic. Love is of two types: Prohibited, which is glorifying the beauties of foreign women and engaging in romantic conversations that ignite desire. A believer must avoid this, stay away from bad company, occupy themselves with what benefits, and hasten to marry if able. And Praiseworthy, which is love for the sake of Allah.
