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.  

مَا غِرْتُ لِلنَّبِيِّ ﷺ عَلَى امْرَأَةٍ مِنْ نِسَائِهِ مَا غِرْتُ عَلَى خَدِيجَةَ لِكَثْرَةِ ذِكْرِهِ إِيَّاهَا وَمَا رَأَيْتُهَا قَطُّ  

[Machine] "I have never been jealous of any woman as I have been jealous of Khadijah, and that was only because of the Prophet Muhammad's frequent mention of her."  

«مَا غِرْتُ عَلَى امْرَأَةٍ مَا غِرْتُ عَلَى خَدِيجَةَ وَمَا ذَاكَ إِلَّا لِكَثْرَةِ ذِكْرِ رَسُولِ اللهِ ﷺ إِيَّاهَا»  

[Machine] "I have not envied any of the wives of the Messenger of Allah, ﷺ , as I have envied Khadijah for his mentioning of her."  

«مَا غِرْتُ عَلَى أَحَدٍ مِنْ نِسَاءِ رَسُولِ اللهِ ﷺ مَا غِرْتُ عَلَى خَدِيجَةَ مِنْ كَثْرَةِ ذِكْرِهِ لَهَا ﷺ»
