If any servant (of Allah) who suffers a calamity says:" We belong to Allah and to Him shall we return; O Allah, reward me for my affliction and give me something better than it in exchange for it," ' Allah will give him reward for affliction, and would give him something better than it in exchange. She (Umm Salama) said: When Abu Salama died. I uttered (these very words) as I was commanded (to do) by the Messenger of Allah ﷺ. So Allah gave me better in exchange than him. i. e. (I was taken as the wife of) the Messenger of Allah ﷺ.  

أَنَّهُ سَمِعَ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ ﷺ تَقُولُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا مِنْ عَبْدٍ تُصِيبُهُ مُصِيبَةٌ فَيَقُولُ إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ اللَّهُمَّ أْجُرْنِي فِي مُصِيبَتِي وَأَخْلِفْ لِي خَيْرًا مِنْهَا إِلاَّ أَجَرَهُ اللَّهُ فِي مُصِيبَتِهِ وَأَخْلَفَ لَهُ خَيْرًا مِنْهَا قَالَتْ فَلَمَّا تُوُفِّيَ أَبُو سَلَمَةَ قُلْتُ كَمَا أَمَرَنِي رَسُولُ اللَّهِ ﷺ فَأَخْلَفَ اللَّهُ لِي خَيْرًا مِنْهُ رَسُولَ اللَّهِ ﷺ  

[Machine] I heard the Messenger of Allah ﷺ saying, "No servant is afflicted with a calamity and says, 'Indeed, we belong to Allah, and indeed to Him we will return. O Allah, reward me in my affliction and replace it for me with something better, except that Allah will reward him in his affliction and replace it for him with something better.' When Abu Salama passed away, I said, 'Who is better than Abu Salama, the companion of the Messenger of Allah ﷺ ?' Then it was determined for me and I said it, and I married the Messenger of Allah ﷺ ."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَا مِنْ عَبْدٍ تُصِيبُهُ مُصِيبَةٌ فَيَقُولُ إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ اللهُمَّ أْجُرْنِي فِي مُصِيبَتِي وَاخْلُفْ لِي بِخَيْرٍ مِنْهَا إِلَّا آجَرَهُ اللهُ فِي مُصِيبَتِهِ وَخَلَفَ لَهُ خَيْرًا مِنْهَا» فَلَمَّا تُوُفِّيَ أَبُو سَلَمَةَ قُلْتُ مَنْ خَيْرٌ مِنْ أَبِي سَلَمَةَ صَاحِبِ رَسُولِ اللهِ ﷺ؟ ثُمَّ عَزَمَ لِي فَقُلْتُهَا فَتَزَوَّجْتُ رَسُولَ اللهِ ﷺ
