This is the dua that Umm Salama (ra) made as taught to her by Abu Salama (ra) as taught to him by the Prophet (salAllahu alayhi wa salam) which resulted in Allah giving Umm Salama (ra) the Prophet (salAllahu alayhi wa salam) as a husband when Abu Salama (ra) passed away.
May Allah grant best replacement to all those who have lost their husbands Ameen
