Ayesha reported,

I never felt jealous of any of the Prophet's ﷺ wives as I did of Khadijah, though she had died before he married me. This was because of how often I would hear him mention her, and because Allah had commanded him to give her glad tidings of a house in Paradise made of hollow pearls. Whenever he slaughtered a sheep, he would send portions of it to her close friends, sharing it generously among them.

عن عائشة رضي الله عنها قالت

ما غرت على امرأة للنبي ﷺ ما غرت على خديجة هلكت قبل أن يتزوجني لما كنت أسمعه يذكرها وأمره الله أن يبشرها ببيت من قصب وإن كان ليذبح الشاة فيهدي في خلائلها منها ما يسعهن
