I never felt jealous of any of the wives of the Prophet ﷺ as much as I felt jealous of Khadijah, even though I never met her. This was only because of how often the Messenger of Allah ﷺ mentioned her. He would slaughter a sheep, then seek out Khadijah's friends and send portions of it to them as gifts.
حدثنا أبو هشام الرفاعي حدثنا حفص بن غياث عن هشام بن عروة عن أبيه
ما غرت على أحد من أزواج النبي ﷺ ما غرت على خديجة وما بي أن أكون أدركتها وما ذاك إلا لكثرة ذكر رسول الله ﷺ لها وإن كان ليذبح الشاة فيتتبع بها صدائق خديجة فيهديها لهن
Agreed upon [by Bukhari and Muslim]. Bukhari narrated it in the Book of the Merits of the Ansar, chapter on the Prophet's ﷺ marriage to Khadijah and her merit, may Allah be pleased with her, hadith no. 3818, and Muslim, hadith no. 2435, from the hadith of Hafs bin Ghiyath, through this same chain.
