i am a shia and i want to marry a sunni girl
Is it permissible in islam and if yes then give me some references that i can show it to my family for to convince them for marriage
give me both reference shia as well as sunni books so i could convince both the sides

There is no issue in this concern you may do this marriage. If anyone who believes in Oneness of Allah and believes that Prophet Muhammad (pbuh) his the last Prophet and believes in the hereafter is called Muslim and according to all Fuqha ( shia Jurists ) permanent marriage amongst Muslims are allowed doesn't matter which sect they are following.
Now if you want proof then our Aimmah's (a.s) life is the best example Imam Hasan (a.s) married w/o Jo'da binte Ash'as.Imam Mohammad Taqi al- Jawad (a.s) married with Ummul Fa daughter of Mamoon (Abbaside caliph).
there are many examples in history.
But you can't find any written proof in any book where has written that being a shia a person can't marry with a Sunni girl. Yes if are worry that you and your generation's faith would be affected your with this marriage then better not to do so otherwise there is no issue in doning such marriage.Later it would be your duty to convince your spouse to the faith of Ahlul bayt (a.s) to secure your future generations.

I live in Sweden and it's normal to use makeup here. My skin doesn't look even, some places look darker than others, like for example under my eyes. Is it okey to use some foundation to just even out the color on my face and hide any irregularities? It will look like I have clearer skin but it won't look like I'm using a lot of makeup. Also it won't look like I'm tired or sick. Here in Sweden it's more common to use makeup than not. So if I don't it will attract more attention that what it would if I used a small amount.

as for as make up concern it is not permissible to have make-up for non mahram in such a way that it could be considered as a Zeenat ( adornment) and this is not allowed.But what people think if you don't do much more make is not a criteria in Islam.Yes if some kinds of make-up is because of its frequent use now considered as a normal thing in a society then one can have such make-up with this intention to protect her skin but not to showoff (May Allah forgiven us).

If you are in state of haiz (najasath due to periods) can you view the dead body or be present at the funeral and can you pray namaaz e mayyit?

At the time of last movement (ehtizar)it is makrooh to stay but after that it is ok as for as namaz concern one can pray

Sister please advice on the following issue--- in western part of world normally we make ghusl in shower. So after cleaning body, i make niyyat of wajib ghusl , and while standing under shower i first wash head and neck while saying niyyat 3 times, then turn my right side of body under shower and repeat the niyyat 3 times and then do the same for left part of body, shoulder to foot.
Is this a wrong method??
I saw a video clip where one moulana says that i have to step out of shower after each part is washed like head to neck is one, right side is 2nd and so on

In ghusl only once you make niyyat before starting is enough no need to repeat 3 times and no need to do niyyat before washing each part just do niyyat once before starting ghusl and washing each part under shower is ok. rule no 367 is saying , while standing under the water jerks each of these parts on one's body with an intention of performing tartibi ghusl,it will not be sufficient. but in your case u r turning your body so it is right way.

I believe I need to verify on my condition with menstrual cycle. So I start on my day as expected with just a sign but no flow. For 2-3 days iam in this condition of nit a runny flow but stain. Is this haeez?
Secondly it showed on 10th day after i did my wajib ghusl to clean from haeez. Do i do ghusl with niyyat of haeez again on 11th day or do niyyat of istehaza.

If bleeding start in your cycle date and it continues more than 3 days then you consider it as hayz but if it is going on more than 10 days so after 10 days you have to pray namaz and follow the rules of istihaza

Well, i am making ghusl everyday as i consider i am in little or medium istehaza
While doing ghusl i fo niyyat of istehaza
Is it correct

if it is little ghusl not needed only wudhu and make yourself pak and change you pad but if it is medium then one ghusl par day and for rest namaz follow the rules of little

I first take normal bath with soap and shampoo then do niyat of ghusl and then pour two jugs of water on head then two or three jugs on right should then two or three jugs on left shoulder without using hand..Is it right ?? If not please correct me

First of all you have to wait until brown and yellow discharge goes out completely. and there is no need of check every movement. and if after becoming pak ghusl is not possible do tayamum and pray namaz. when u r doing ghusl jug is not a criteria . important is a this that water should reach all your body parts completely

Reciting Quran, salwat or namaz for the dead people so that they get the benefit of it will benefit us too? will we also get the reward of reciting it though we aren't reciting it for ourselves but for the dead people

Yes of course there is no doubt Allah will give you equal thawab we have in Quran chapter 55 verse 60 is the reward of goodness aught but goodness.

How should a women put water on her hand while doing ablution... should it be started from the front side or back side of hand?

salam for women it is mustahab it be started from the front side

While making wuzu should one splash water several times on its face and then do the masa? or one should directly take a handful of water and then do masa?

for masa you have not to take water from outside . you have to do masa with same water which is remaining after washing of your hands from elbow until middle finger tip.
