I heard Messenger of Allah ﷺ saying (as below) Narrated ʿAli: The Prophet ﷺ said, "The best of the world's women is Mary (at her lifetime), and the best of the world's women is Khadija (at her lifetime).  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ ح حَدَّثَنِي صَدَقَةُ أَخْبَرَنَا عَبْدَةُ عَنْ هِشَامٍ عَنْ أَبِيهِ قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ جَعْفَرٍ عَنْ عَلِيٍّ ؓ عَنِ النَّبِيِّ ﷺ قَالَ خَيْرُ نِسَائِهَا مَرْيَمُ وَخَيْرُ نِسَائِهَا خَدِيجَةُ  

I did not feel jealous of any of the wives of the Prophet ﷺ as much as I did of Khadija (although) she died before he married me, for I often heard him mentioning her, and Allah had told him to give her the good tidings that she would have a palace of Qasab (i.e. pipes of precious stones and pearls in Paradise), and whenever he slaughtered a sheep, he would send her women-friends a good share of it.  

مَا غِرْتُ عَلَى امْرَأَةٍ لِلنَّبِيِّ ﷺ مَا غِرْتُ عَلَى خَدِيجَةَ هَلَكَتْ قَبْلَ أَنْ يَتَزَوَّجَنِي لِمَا كُنْتُ أَسْمَعُهُ يَذْكُرُهَا وَأَمَرَهُ اللَّهُ أَنْ يُبَشِّرَهَا بِبَيْتٍ مِنْ قَصَبٍ وَإِنْ كَانَ لَيَذْبَحُ الشَّاةَ فَيُهْدِي فِي خَلاَئِلِهَا مِنْهَا مَا يَسَعُهُنَّ  

I did not feel jealous of any woman as much as I did of Khadija because Messenger of Allah ﷺ used to mention her very often. He married me after three years of her death, and his Lord (or Gabriel) ordered him to give her the good news of having a palace of Qasab in Paradise.  

مَا غِرْتُ عَلَى امْرَأَةٍ مَا غِرْتُ عَلَى خَدِيجَةَ مِنْ كَثْرَةِ ذِكْرِ رَسُولِ اللَّهِ ﷺ إِيَّاهَا قَالَتْ وَتَزَوَّجَنِي بَعْدَهَا بِثَلاَثِ سِنِينَ وَأَمَرَهُ رَبُّهُ ﷻ أَوْ جِبْرِيلُ عَلَيْهِ السَّلاَمُ أَنْ يُبَشِّرَهَا بِبَيْتٍ فِي الْجَنَّةِ مِنْ قَصَبٍ  

I did not feel jealous of any of the wives of the Prophet ﷺ as much as I did of Khadija though I did not see her, but the Prophet ﷺ used to mention her very often, and when ever he slaughtered a sheep, he would cut its parts and send them to the women friends of Khadija. When I sometimes said to him, "(You treat Khadija in such a way) as if there is no woman on earth except Khadija," he would say, "Khadija was such-and-such, and from her I had children."  

مَا غِرْتُ عَلَى أَحَدٍ مِنْ نِسَاءِ النَّبِيِّ ﷺ مَا غِرْتُ عَلَى خَدِيجَةَ وَمَا رَأَيْتُهَا وَلَكِنْ كَانَ النَّبِيُّ ﷺ يُكْثِرُ ذِكْرَهَا وَرُبَّمَا ذَبَحَ الشَّاةَ ثُمَّ يُقَطِّعُهَا أَعْضَاءً ثُمَّ يَبْعَثُهَا فِي صَدَائِقِ خَدِيجَةَ فَرُبَّمَا قُلْتُ لَهُ كَأَنَّهُ لَمْ يَكُنْ فِي الدُّنْيَا امْرَأَةٌ إِلاَّ خَدِيجَةُ فَيَقُولُ إِنَّهَا كَانَتْ وَكَانَتْ وَكَانَ لِي مِنْهَا وَلَدٌ  

I asked ʿAbdullah bin Abi ʿAufa, "Did the Prophet ﷺ give glad tidings to Khadija?" He said, "Yes, of a palace of Qasab (in Paradise) where there will be neither any noise nor any fatigue."  

قُلْتُ لِعَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى ؓ بَشَّرَ النَّبِيُّ ﷺ خَدِيجَةَ قَالَ نَعَمْ بِبَيْتٍ مِنْ قَصَبٍ لاَ صَخَبَ فِيهِ وَلاَ نَصَبَ  

Gabriel came to the Prophet ﷺ and said, "O Messenger of Allah ﷺ! This is Khadija coming to you with a dish having meat soup (or some food or drink). When she reaches you, greet her on behalf of her Lord (i.e. Allah) and on my behalf, and give her the glad tidings of having a Qasab palace in Paradise wherein there will be neither any noise nor any fatigue (trouble) . "  

أَتَى جِبْرِيلُ النَّبِيَّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ هَذِهِ خَدِيجَةُ قَدْ أَتَتْ مَعَهَا إِنَاءٌ فِيهِ إِدَامٌ أَوْ طَعَامٌ أَوْ شَرَابٌ فَإِذَا هِيَ أَتَتْكَ فَاقْرَأْ عَلَيْهَا السَّلاَمَ مِنْ رَبِّهَا وَمِنِّي وَبَشِّرْهَا بِبَيْتٍ فِي الْجَنَّةِ مِنْ قَصَبٍ لاَ صَخَبَ فِيهِ وَلاَ نَصَبَ  

Once Hala bint Khuwailid, Khadija's sister, asked the permission of the Prophet ﷺ to enter. On that, the Prophet ﷺ remembered the way Khadija used to ask permission, and that upset him. He said, "O Allah! Hala!" So I became jealous and said, "What makes you remember an old woman amongst the old women of Quraish an old woman (with a teethless mouth) of red gums who died long ago, and in whose place Allah has given you somebody better than her?"  

قَالَتِ اسْتَأْذَنَتْ هَالَةُ بِنْتُ خُوَيْلِدٍ أُخْتُ خَدِيجَةَ عَلَى رَسُولِ اللَّهِ ﷺ فَعَرَفَ اسْتِئْذَانَ خَدِيجَةَ فَارْتَاعَ لِذَلِكَ فَقَالَ اللَّهُمَّ هَالَةَ قَالَتْ فَغِرْتُ فَقُلْتُ مَا تَذْكُرُ مِنْ عَجُوزٍ مِنْ عَجَائِزِ قُرَيْشٍ حَمْرَاءِ الشِّدْقَيْنِ هَلَكَتْ فِي الدَّهْرِ قَدْ أَبْدَلَكَ اللَّهُ خَيْرًا مِنْهَا
