Saudi Arabia deals in riba and allows tobacco products to be sold! Does this make it halal?

sheikh In Islam a woman is not allowed to travel without a mahram, then why is it that Saudi Arabia allows women over 45 to go for umrah and haj with a group. This is arranged with the travel agents in Canada. They have been doing this , pls elaborate on this.

In Pakistan it is a very common trend that when someone goes for hajj and umrah ppl say to him ‘plz pay my salam at the rawdah and say my salam to kabaah. Plus ppl ask the person who is going to make specific duas for themselves. Can we ask others to make duas for us and pay our salams?

Is the fidiya to be given for leaving an obligatory part (wajib) of Hajj and the fidiya to be given for doing something prohibited in ihram are the same? Or sacrifice is the only option for leaving an obligatory part of Hajj?
