question is

1) how and when was the current format of oosool e diin and furoo e diin formed
various ahaadiis and aayaat point out to the same but the current format was not designed by masooms

2) how much right or wrong can it be (not the belief, I mean the order of placement)

3) why is it not biddah if it was comprised later on

4) as Adal is a part of Tauhiid why is it mentioned seperate

5) as Imaamat is a part of Nabuwat why is it mentioned seperate

There are even more things that are essential belief of religion than the ones commonly mentioned. These 5 and 10 usul and furu e deen are just the ones that are commonly known and mentioned which are extracted from our ahadith of the imams (as).

where do I look for more detailed knowledge into the same
there are so many puzzling things goings on

A good book is Aqaed Imamiyya (Faith of Shia Islam) by Allama Muzaffer

1. Whats is the meaning of Rekigion in general and also in Islam.

2. What is the meaning of Deen in general and in Islam.

explain with example...

Religion is the English translation for the word Deen. Deen means a way of life which for us is our religion.

Is Fidya and kaffara the same?
can i pay $5 per fast not paid due to Hayz??

https://www.imam-us.org/qada-fasts-kaffarah-1439/

1)when is the right time for closing fast....is it 13 min before fajr or at fajr?
2)can the fast be opened right after praying Maghrib salah with water.....then continue with Ishaa namaz?

You should use precaution and stop eating a few minutes before fajr.

Customarily you end the fast at the adhan of Maghrib then make salat al maghib and isha

Rule 1559 from Ayatollah Sayed Sistani says it is better to wait a little bit after Maghrib has set in as a means of precaution.

My question is i have a fear of namaz all the time but i am mostly missing my namaz and sometimes delay in praying it until the last moment. please advise why is it. whereas i always have the fear in my heart that as i am missing the most important aspect of Salah. how to solve this moulana. Also sometimes my job work and my housework, delays and tires me off which also is the reason at times for the delay but i dont want that as an excuse and want to be very keen at performing my salah.

Try to make your prayers at the earliest time possible so that you do not get tired and delay them. You can set alarm to remind you of the prayer times and also they have apps on the phones for this. Always keep your salat first and schedule your other things around the salat and not the opposite of trying to fit your salat into your schedule. I hope this will help you inshallah.

My son has a problem with his speech and he cannot speak looking into anyone's eyes, which is a big problem for us in his admission in school. Also, he has become very stubborn and is minor autistic child. please help is to cure him with some surahs and amals.

I have a question so i was fasting all day yesterday and went to sleep 2hrs before iftar and woke up the next day at 5:30 am past imsak I continued fasting but i don't think i can handle it any longer

If it becomes unbearable on you and you fear for your health then it is permissible to break your fast and do qadha

Could you please tell how to dua from allah subhanotallah since I directly ask allah and make my haajat do I have to give the wasila of 14 masoomeen when I make dua?

You can make du’a and ask Allah directly without making tawassul. It is more preferred that you ask by the right of Ahl ul Bayt (as) to grant your need. Also, you can make a Nazr (vow) that if your need is granted then you will do some good deed (specify the deed) and dedicate that reward to the 12th Imam (aj) for example or any other Infallibles (as).

I have a 17yr old son very rebellious. Recently I have caught drugs in his room and he has denied the usage. He doesn't want to accept that he is wrong. For studies he has all types of excuses. He neither offer namaaz nor wants me to tell him about religion. Only he follows moharram that too without attending any majalis. He doesn't want to listen anything. As a mother I'm too worried and desperate .

I am very sad to hear this. Inshallah he can make it out of this spiritual rut. I would suggest that you have him watch this show with you and perhaps it will open his eyes.
