The relationship between the children from a woman's second husband and the children of her ex-husband from his first wife

A: There is no relation between the second wife's children from her second husband and the children of her ex-husband from another wife, either through lineage or affinity, unless there has been breastfeeding, which affects marriageability between the said children.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
