Is it haraam to make models of kaba and explain the children the rituals of hajj?

I wasnt aware that ramadan fasts missed due to menstruation had to be made up before nafl ones and I started keeping some nafl ones so is it possible for me to change the intention of the previous nafl ones I have kept or to change the intention of fast during the day? Because the one I kept today for example I started off with the intention of keeping a nafl fast but can I now change this to the intention of making up the ones I missed in ramadan?

A Muslim woman swore that she would not speak to another Muslim woman because of a dispute that had arisen between them. Then the other woman sent her several text messages, repeatedly, so the first woman responded by a text message. Now the first woman is asking: do I have to offer expiation for breaking an oath or not? What should I do if I want to talk to her again?.

I embraced Islam -praise be to Allah- and now I want to keep myself chaste, but my parents think that the most suitable age of marriage is not until twenty-five or preferably twenty-eight. Even worse than that, one of them thinks that there is nothing wrong with friendship and relationships outside of marriage - Allah forbid. The matter is extremely difficult and I do not know how to talk to them about this matter. I want to keep myself chaste; I want to marry a man who will help me to adhere to my religion, a man who will stand beside me and help me, a man who will live with me, because I am living far away from my parents. They are divorced and each one lives in a different city. I do not know how to explain these details to them in order to convince them that I should get married early; rather they think that getting married at an early age is something that is not appropriate. I am the only daughter of my parents, hence I do not want to disobey them and I do not want to upset them; I do not want them to forsake me either. I want at least to do the marriage contract, then delay consummation until Allah wills.

My questions are:

1. Is it permissible for me to do the marriage contract but delay marriage and the waleemah (wedding feast) and consummation for five years, for example?

2.  Do I have to repeat the marriage contract in front of my family later on and pretend that I was not married? Or is that regarded as coming under the heading of lying? I hope you can advise me because I do not know what to do.
 

I live and work in UK. In order to get extra welfare benefits to help pay my rent and local council taxes (on top of national taxes) I am showing less income (earnings). By doing so I get extra money which helps pay various bills and I save some as well. Is this permissible? Is this income Haram? Is the whole amount of benefit I get Haram or parts?

In order for a person to be allowed to sit during the obligatory prayers, is it essential that he should be completely unable to stand? Or is it also permissible for a person who is able to stand, but it is possible that it may lead to harm? What is the definition of the inability that makes it permissible to sit during the prayer and not stand, without that incurring sin or punishment?.

I am a young Muslim man who believes in Allah and His Messengers and His Books, praise be to Allah. But sometimes I feel too lazy to pray. I am looking for a solution and a way to make me not be so lazy. Please note that this is what I want but the tricks of the Shaytaan are too strong.

What is the ruling on fasting six days of Shawwaal? Is it waajib (obligatory)?
