Ayesha reported,
"I was never as jealous of any of the Prophet's ﷺ wives as I was of Khadijah, even though she had died before he married me, because of how often I heard him mention her. 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, enough to suffice them."
Azami 10376
Sahihعن عائشة قالت
ما غرت على امرأة للنبي ﷺ ماغرت على خديجة، هلكت قبل أن يتزوجني لما كنت أسمعه يذكرها، وأمره الله أن يبشرها ببيت من قصب، وإن كان ليذبح الشاة فيهدي في خلائها منها ما يسعهن.
Bukhari narrated it in the Virtues of the Ansar (3816), and Muslim in the Virtues of the Companions (2435), both through Hisham, from his father, from Ayesha, who said, and then mentioned it. This is Bukhari's wording, and Muslim's wording is similar, but he added, after the words "that he marry me", the phrase "three years later", just as he added, after the words "of reeds", the phrase "in Paradise". In one wording, "She said, and he married me three years after that, and his Lord 
, or Jibreel 
, commanded him to give her the glad tidings of a house of reeds in Paradise."Bukhari narrated it in the Virtues of the Ansar (3817), from Qutayba bin Saeed, who said, Humayd bin Abdul-Rahman narrated to us, from Hisham bin Urwa, from his father, from Ayesha, who said, and then mentioned it.
