I never felt so jealous of any wife of Allah's Messenger (ﷺ) as I did of Khadija because Allah's Messenger (ﷺ) used to remember and praise her too often and because it was revealed to Allah's Messenger (ﷺ) that he should give her (Khadija) the glad tidings of her having a palace of Qasab in Paradise .
Sahih al-Bukhari Book 67, Hadith 162
← Previous Hadith That Allah's Messenger (ﷺ) said to her, "I know when you are pleased with me or angry with me." I said, "Whence do you know that?" He said, "When you are pleased with me, you say, 'No, by the Lord of Muhammad,' but when you are angry with me, then you say, 'No, by the Lord of Abraham.' " Thereupon I said, "Yes (you are right), but by Allah, O Allah's Messenger (ﷺ), I leave nothing but your name."

Sahih al-Bukhari Book 67, Hadith 161 Next Hadith → I heard Allah's Messenger (ﷺ) who was on the pulpit, saying, "Banu Hisham bin Al-Mughira have requested me to allow them to marry their daughter to `Ali bin Abu Talib, but I don't give permission, and will not give permission unless `Ali bin Abi Talib divorces my daughter in order to marry their daughter, because Fatima is a part of my body, and I hate what she hates to see, and what hurts her, hurts me."

Sahih al-Bukhari Book 67, Hadith 163
