Travelling without a Mahram

Woman travelling without a mahram

Q: Please advise on the following situation: 

My wife has one sister, who is younger than her and unmarried. Their mother passed away last year. Her sister is working and currently stays alone. 

My wife has asked if her sister can join us on holiday as she has no one to travel with. 

Furthermore, my wife has proposed that if I do not agree to her sister joining us on holiday, she will have no option but to travel alone with her sister and our children to either Durban or Cape Town.

 My wife does not feel comfortable leaving her sister alone at home, nor does she feel comfortable with her sister travelling alone. 

Please advise if any of these options put forward by my wife are permissible. Are there any other options that can be considered?

Good actions of a woman who travels without a mahram being affected

Q: There is a hadith about women travelling, Abu Hurairah (radhiyallahu anhu) reported: The Messenger of Allah (sallallahu alaihi wasallam) said, 

"It is not permissible for a woman who believes in Allah and the last day to make a journey of one day and night unless she is accompanied by a mahram (husband or male relative whom she is prohibited to marry)." (Al Bukhari and Muslim) 

According to the hadith, if a woman travels alone will her prayers not be accepted?

Q: I want to ask about travelling alone. My sister lives in Australia and she wants to visit us in India. She cannot come with her husband or son because of their work and school. My other sister is also coming from Saudi with her children so we can reunite as my mother is not well

My question is, is it permissible for her to travel alone as she is confused?
