Is a Salafi child who was nursed by another mother considered a brother to all of her children, or only to the one with whom he was nursed?

The suckling that prohibits marriage is five sucklings. The definition of a suckling is determined by common practice. Jurists consider a suckling to be when the child takes the breast and sucks from it, then leaves it. If this occurs five times in one sitting, then the prohibitive suckling is established. The suckling child becomes a sibling to all those born to his wet nurse, and to the one who breastfed him, whether he suckled with her, before her, or after her.
