question #2 Sahih al-Bukhari 6004, Book 78, Hadith 35 : How does the concept of jealousy manifest in relationships according to Islamic teachings?

I never felt so jealous of any woman as I did of Khadija, though she had died three years before the
Prophet married me, and that was because I heard him mentioning her too often, and because his Lord
had ordered him to give her the glad tidings that she would have a palace in Paradise, made of Qasab
and because he used to slaughter a sheep and distribute its meat among her friends.
