`Abdullah b. Ja`far reported that he heard `Ali say in Kufa that Allah's Messenger (ﷺ) said
The best of the women of her time was Mary, daughter of `Imran, and the best of the women of her time was Khadija, daughter of Khuwailid. Abu Kuraib said that Waki` pointed towards the sky and the earth.
Abu Musa reported Allah's Messenger (ﷺ) as saying
There are many persons amongst men who are quite perfect but there are none perfect amongst women except Mary, daughter of 'Imran, Asiya wife of Pharaoh, and the excellence of 'A'isha as compared to women is that of Tharid over all other foods.
Abu Huraira reported that Gabriel came to Allah's Apostle (ﷺ) and said
Allah's Messenger, lo. Khadija is coming to you with a vessel of seasoned food or drink. When she comes to you, offer her greetings from her Lord, the Exalted and Glorious, and on my behalf and give her glad tidings of a palace of jewels in Paradise wherein there is no noise and no toil. This hadith has been narrated on the authority of Abu Huraira through another chain of transmitters with a slight variation of wording.
Ismail reported
I said to 'Abdullah b. Abi Aufa: Did Allah's Messenger (ﷺ) give glad tidings of Paradise to Khadija? He said: Yes. He did give glad tidings to her of a palace of jewels in Paradise wherein there would be no noise and no toil.
This hadith has been narrated on the a tliority of Ibn Abi Aufa through other chains of transmitters.
'A'isha reported that Allah's Messenger (may peace he upon him) gave glad tidings to Khadija bint Khuwailid of a palace in Paradise.
'A'isha reported
Never did I feel jealous of any woman as I was jealous of Khadija. She had died three years before he (the Holy Prophet) married me. I often heard him praise her, and his lord, the Exalted and Glorious, had commanded him to give her the glad tidings of a palace of jewels in Paradise: and whenever he slaughtered a sheep he presented (its meat) to her female companions.
'A'isha reported
Never did I feel jealous of the wives of Allah's Apostle (ﷺ) but in case of Khadija, although I did no, (have the privilege to) see her. She further added that whenever Allah's Messenger (ﷺ) slaughtered a sheep, he said: Send it to the companions of Khadija I annoyed him one day and said: (It is) Khadija only who always prevails upon your mind. Thereupon Allah's Messenger (ﷺ) said: Her love had been nurtured in my heart by Allah Himself.
This hadith has been transmitted on the authority of Abu Usama up to the slaughtering of a sheep, but he. did not make mention of the subsequent words.
'A'isha reported
Never did I feel jealous of any wife amongst the wives of Allah's Apostle (ﷺ) as I feel in case of Khadija (though I had never seen her), for he praised her very often.
'A'isha reported that Allah's Apostle (ﷺ) did not marry any other woman till her (Khadija's) death.
A'isha reported that Hala b. Khuwailid (sister of Khadija) sought permission from Allah's Messenger (ﷺ) to see him and he was reminded of Khadija's (manner of) asking leave to enter and (was overwhelmed) with emotions thereby and said
O Allah, it is Hala, daughter of Khuwailid, and I felt jealous and said: Why do you remember one of those old women of the Quraish with gums red and who is long dead-while Allah has given you a better one in her stead?
