I dont see in this day and age with the motor car and areoplane in times of peace is the same as when the Prophet(pbuh) was alive during times of war where his enemies were around.
I could drive my wife to the airport that has ott security where in less time it takes to cross a city by foot she could be the other side of/or in a different continet with less danger than walking across a city..She could get in safe transport and arrive with her family or friends safer than walking accross a city and in less time.
Now i agree its good advice and better to have a guardian, especially if going on a spiritual journey together as man and wife or as a family, like a going on a pillgrimage, but the situation on simple travel has changed a great deal since the times of the Prophet (pbuh)..
Allha puts these man made laws into prespective and explains why no man can create a law that will stand the test of time..I respect the haiths but find them problematic when men take something the Propet said then make a rule out of it for all people for all time when its not going to stand the test of time.
And there are other rules that go against what the Prophet (pbuh) said, it seems the deeper i look much of whats called islam is man made, no offence, inshalla.
If we could accept it as advice, fair enough, but when it can become an enforcable law, its a problem that will casue harrasment of women and trurn people away from the Truth that is Islam the salvation for mankind.
"Unto me my work, and unto you your work. Ye are innocent of what I do, and I am innocent of what ye do"
Then bring a surah like unto it, and call (for help) on all ye can besides Allah, if ye are truthful.39 Nay, but they denied that, the knowledge whereof they could not compass, and whereof the interpretation (in events) hath not yet come unto them.
Only Allahas word can stand the test of time, if this rule was worthy He would of surley revealed it?
No, this modern age is more corrupted than previous one, let alone the age of prophet s.a.w
