Eid gifts

Q: I noticed that people are giving "eid gifts" in the same way as the non muslims are giving "Christmas gifts". Is this a practice of Nabee (Sallallahu Alayhi Wasallam) or an innovation? I can not remember any such custom when we were children.

Husband ill treating the wife

Q: A lady is often taunted by her husband on various matters, his favourite taunt is "You are a Jahnami". This upsets her because she tries her best at being a good wife, she does not do anything or go anywhere without his permission, she looks after the family and home, she prays all her salahs regularly and she prays the Quran every day as much as she can, but her husband is never happy and always looks for excuses to embarrass her in front of other people, sometimes he pushes her to the limit, and when she's praying he tells her that she shouldn't bother because non of her ibaadat will be accepted. When she's in sajda, he tells her to stop doing that because she's wasting her time,whilst he does not pray namaz at all. He only goes to pray 1 juma in a month. When she tells him to pray namaz, he tells her to mind her own business. He deliberately makes her look for things that he knows are not there, he will first look in the fridge or the kitchen cupboards to see what food is not in stock, and then later he will ask her to give him that food to eat and if she says it's finished, he starts swearing at her, so she goes to shop to get it and then give it to him, but then he won't eat it because he will say he doesn't want it anymore. She has now had enough and is thinking of leaving him, but before she takes that action, is there anything she can pray, any wazifa that might make him a good husband and make him a namazi?

Inheritance

Q: My question is about distribution of property according to sunni shariat. My mom has 2 sisters. Out of my two aunts only one has children of which are daughters. My other aunt doesn't have any children. My mom is the only one with a son. So after the Death of my aunt the property is to be distributed between her sisters, i.e my mom and aunt since my other aunt did not have any children. So my actual question is that should my mom receive the property in 2:1 ratio since she has a son?
