Re: Hajj/Umrah with kids?
No, going to madinah is not a requirement of hajj. The forty namaz thing comes from some Hadith (which I have never read myself so am not sure) which basically says that if u prayed 40 namazs’ in the madinah mosque then the Prophets intercession becomes wajib on u on the day of judgement. I have nno idea if this is a strong or weak Hadith or if it really is one, because I haven’t come across it (as in I didn’t search for it but otherwise have never randomly read it).
