Death of Abu Salama RA

إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ ، اللَّهُمَّ أْجُرْنِي فِي مُصِيبَتِي وَأَخْلِفْ لِي خَيْرًا مِنْهَا

Never does anyone afflicted with a calamity and he is patient at that and makes this du'a, except that Allah will surely reward him for it and replace it for him with a better thing: "Indeed, we belong to Allah, and indeed, to Him we will return. O Allah, reward me for my calamity, and replace it for me with that which is better."

Later relayed by Abu Salama RA to Umm Salama RA, who recited it herself after his death.

My husband came home very happy and said, "I heard a beautiful hadith from the Prophet ﷺ!" As soon as Abu Salama died, I remembered this hadith, so I said the du'a. But deep down I said to myself, "Who can possibly be better than Abu Salama?"

Umm Salama RA's own later recollection.

I have heard that if a man of Jannah dies and his wife never remarries, she will automatically go to Jannah with him, and if a woman of Jannah dies and her husband doesn't remarry, they will be reunited in Jannah too. So let's make a promise to each other that we are not going to marry if one of us dies.

On Abu Salama RA's deathbed.
