Incorrect pronunciation in tashahhud

Q: I have one major problem during salaah and that is that I cannot pronounce in the tahiyyaat the last letter (n) of the word " as saliheen" especially during the first tashahhud. So I keep repeating it, until I manage to pronounce it. If I will recite it as "as salihee" without the last letter "n" would that be also valid and the meaning still correct? Or should I recite like "as salih" without "een" at the end, like the tanween we do not recite at end of ayaats?

Touching one's mother in-law with lust

Q: An accident occurred in bus journey some years ago, that is: my mother in law's seat was beside my seat. She was feeling ill because of some illness but I was feeling lust/desire but not highly exited. Then I probably touch her (not her private part). But I was mentally addicted by shaitan’s waswasa. She didn't know this was my situation. I had no idea before about marriage, mahrams and hurmat-e-mushara. After I came to know about hurtmat-e-musaahara, I repented and made Towba to Allah Ta'ala. Now I am very alert about shaitan’s waswasa. But mentally I am worried about that accident. Now my wife would be lawful? I have one daughter. Please clearly advise me.

Travelling without a mahram

Q: Please can you advise if the following question posed and answered is correct? Especially the point mentioned that it is haraam for females to spend a night without a Mahram even if the journey is less than 78km.

Question; Is it permissible for a woman to travel for more than 78km without a mahram?

Answer; Aishah (R.A) reports that had Nabi (Sallalahu Alayhi Wasalam) witnessed the condition of women today (period just after the demise of Nabi Sallalahu Alayhi Wasaalm) he would certainly have prohibited them from the Masaajid, as the women of Bani Israeel were prohibited. (Bukhari). When the above Hadith prohibits women going to Musjid because of fitnah, there will be no absolute not leeway for women travelling without a Mahram. It is Haraam for females to spend the night without a Mahram even if the journey is less then 78km.

And Allah knows best.

Also can you please give the shariah ruling on a group of females going on a weekend trip within 78km?
