ANSWER:
Umm Salamah (May Allah be pleased with her) reported:
I heard the Messenger of Allah (ﷺ) saying, “When a person suffers from a calamity and utters: ‘Inna lillahi wa inna ilaihi raji’un. Allahumma ujurni fi musibati, wakhluf li khairan minha (We belong to Allah and to Him we shall return. O Allah! Compensate me in my affliction, recompense my loss and give me something better in exchange for it), then Allah surely compensates him with reward and better substitute. ” Umm Salamah (May Allah be pleased with her) said: When Abu Salamah (May Allah be pleased with him) died, I repeated the same supplication as the Messenger of Allah (ﷺ) had commanded me (to do). So Allah bestowed upon me a better substitute than him (I was married to Muhammad, the Messenger of Allah (ﷺ)). [Muslim]
