Question: My mother was born outside of wedlock due to an illegitimate relationship between my biological grandfather and my biological grandmother. Later he married another woman and has two sons and a daughter from her. My mother married my father and had children including me. My question is are my mum’s half-brothers from this other woman our mahram? Can we go hajj umrah with them? As in, can my aunt from the other woman go hajj with their nephew (my brother).

Answer
In reference to your case scenario, fornication differs significantly from marital relationship, resulting both having different rulings. A mahram relationship between siblings is established through a valid wedlock. A child born outside of wedlock has no established lineage to its biological father but instead is attributed to its biological mother. Your mother therefore has no mahram relationship with her biological father’s legitimate children and henceforth, they do not become your mahram. Traveling to Umrah or Hajj with them as your mahram will not be permitted.[1]
