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

I know that a woman is not permitted to travel without a mahram with her. I would like to know what is meant by (traveling) exactly. Where should we start measuring the distance, from the beginning (a place in the desert), or from where?
My father has a farm on Misr-Ismailia way, and he likes us to visit him every so often, this farm is about 75 minutes maximum from home. Is this considered traveling?
Considering that there are many new cities, schools, companies, and farms along the way.

I am currently living in Canada for the purpose of study, but my permanent place of residence is between Jeddah and Amman. When I stayed in Amman during the summer break, I decided to go to Jeddah to deal with some official papers, and I intended to do ‘umrah if Allah made that possible for me and if I had a mahram and enough time to do ‘umrah. I intended to do ‘umrah from Jeddah because my mahram would be there. But because I was not certain that I would be able to do ‘umrah, on the day I travelled by plane I did not do ghusl, because I was menstruating and I had not yet decided to do ‘umrah. When I got there on the second day I did ghusl and formed the intention to do ‘umrah from Jeddah, and I did it.
My questions are:
Is my ihram from the miqaat of Jeddah considered valid or not?  Because of my family circumstances, we are always moving back and forth between Jeddah and Amman, and we always enter ihram from our house in Jeddah, even if we are on our way back from a trip to Amman and after staying in Jeddah for several days. We do not remember how many times we have done ‘umrah in this manner.
What is required of us if we should have entered ihram from the miqaat for the people of ash-Shaam (Greater Syria)? After I did ‘umrah I was uncertain as to whether I was completely clean following my period. If I think it most likely that I was still menstruating whilst I was doing ‘umrah, what is the ruling on my ‘umrah and what expiation do I have to offer?.

Is it permissible to make phone apps to sell Islamic information? For example, the iPhone mobile phone has a number of apps that are sold via the Apple company, such as the electronic Mushaf, Saheeh al-Bukhaari, Saheeh Muslim, and so on. I would like to make apps like these, that deal with the Qur’an and Prophet’s hadeeths, for the iPhone and iPad, and upload them to the App Store as unique apps.

Can a muslim pray for his non-mulsim mother who has passed away?

My question is regarding distributing leaflets/pamphlets for dawah purposes that contain Quranic verses. It is likely that many of them will end up on the streets or bins after being distributed. Isnt this wrong and should this discourage us giving out such material? Also, is this ok, considering that the targeted recipients are non-muslims who are impure?

I am from a Muslim background, but I never used to offer the obligatory prayers and even when I tried to pray once, I did not do it right. In other words I did not prepare to do it in the proper manner. I ask Allah to forgive me. I heard that the one who does not pray is a disbeliever and is not a Muslim, but whoever offers the five daily prayers, or one or two of them and omits the rest, is regarded as a Muslim. Also, I did not pay zakah on my wealth, but for at least two years I have completed the fast of Ramadan, and I intend to continue doing so. I want to learn how to pray and make it part of my life, along with other acts of worship. 

Is it obligatory for me to pay zakah for all these many years (when I did not pay it), and to make up the days that I did not fast at the time when I was not praying? 

Please note that I have now reached the age of thirty-one years; perhaps you will understand that this may cause me a great deal of hardship; to ward off that hardship, can I start over? Will Allah forgive me if I do that?

How can we help a child to know his Lord?

I want to know about ‘Umrah in detail.

We are three sons, three daughters and a mother. We inherited 14,500 Jordanian dinars from our father and we invested this money in some business; every month we get 215 Jordanian dinars. Is any zakaah due on this amount, because this money belongs to everyone?.

There was a discussion about the issue of putting one’s trust in Allah (tawakkul) and taking measures; the trust of some of the righteous is like that of Maryam, to whom summer fruits used to come in the winter and vice versa without her taking any measures; rather she focused completely on worship. Please advise us about that, may Allah bless you.

There is a saying that treating people equally unfairly is justice; some people attribute this to the Messenger (blessings and peace of Allah be upon him) and some regard it as if it is a basic principle that cannot be changed. What is the Islamic ruling or how sound is this saying?.
