Women's freedom

Q: How did Islaam free the woman? I know about the whole inheritance thing right to divorce and all that. But I feel that saying Islaam freed the women is wrong because it didn’t free us. Its not freedom when your life and life decisions are controlled with your spouse or men in your family. How is that freedom? Like, I am not talking about the haraam freedom and all that. Sometimes I just wish for peace of mind sitting in a cafe that is 7 minutes away but I am not allowed to go unless my spouse feels like I can? While he can go wherever he wants whenever he wants and I am not even allowed to question him. Honestly speaking, I love my Deen so much but recently men make me get disappointed in some parts of it.

Aqeedah of Salafis

Q: Some Ulama from the Deobandi school of thought have included the Salafis as a part of Ahlus Sunnah Wal Jamaa'ah and some haven't. They have done this primarily on the basis of Aqeedah. Someone also told me that Moulana Husayn Ahmed Madani had some 'Salafi' beliefs specifically regarding Aqeedah. After some searching I found it to be true.  If that is the case, and their Aqeedah is also correct, why should we then regard them as deviated? Isn't it just another valid ikhtilaaf from many. 

My second question is that, is there Ijmaa' on the compulsion of following a Mazhab, or is it only for the betterment of this pure Deen of ours?

Taking back a gift

Q: Married sisters gifted their share of property which they received from their father to their brother. After 2 years some dispute occured between the brothers wife and sisters, and now they are saying to return their property.

Is it allowed to take back the gift which they have done earlier?

Greeting with salaam alaikum

Q: Is it ok to just say سلام عليكم? In Hayaatus Sahaabah (Part 2), under chapter 9 -

خروج الصحابة رضي الله عنهم من الشهوات - :التسليم على المسلم - عمل ابي امامة رضي الله عنه في ذالك

A riwaayah comes wherein Abu Umaamah رضي الله عنه said this.
