Narrated Umm Salama (RA): I heard the Messenger of Allah (ﷺ), said: If a servant, in the face of adversity, then says:
إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ، اَللَّهُمَّ أْجُرْنِي فِي مُصِيبَتِي، وَأَخْلِفْ لِي خَيْرًا مِنْهَا
اِنَّا لِلّٰهِ وَاِنَّا اِلَيْهِ رَاجِعُوْنَ، اَللّٰهُمَّ أْجُرْنِيْ فِيْ مُصِيْبَتِيْ، وَاَخْلِفْ لِيْ خَيْرًا مِّنْهَا
Innaa lillaahi wa innaa ilayhi raaji‛oon, Allaahumma’ jurnee fee museebatee, wakhlif lee khayran minhaa
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 surely give him something better than that. After the death of Abu Salamah, I recite this du'a according to the instructions of the Messenger of Allah (ﷺ), then Allah has given me better than him, that is, to the Messenger of Allah (ﷺ).
