Method for strengthening one's imaan

Q: I am a teenager, but I don't read salaah or Qur'aan anymore, and my parents don't enforce it. Whilst living with my grandmother, it was enforced. I don't want to lose my faith. Reading salaah and Qur'aan are becoming difficult. My questions are:

1- how do I regain my faith and just become a better Muslim overall?

2- what books (excluding the Qur'aan) would you recommend for a Muslim to read regardless of the situation?

3- If a person were to begin learning arabic, how would you suggest they go about it?

Looking at animate pictures

Q: If I am reading a book and there is a human picture, will looking at it be sinful? If I am outside and see a picture on a billboard is it haraam to look at? If someone wants to show me a picture of a potential spouse is it haraam to look at? I do not want to incur sin, so please advise me.

Incident of Nabi (sallallahu alaihi wasallam) and an old lady

Q: Is this story true....One day Prophet Muhammad (sallallahu alaihi wasallam) was going somewhere at noon and it was too hot in the desert when He (sallallahu alaihi wasallam) saw an old woman carrying her luggage on her head. Prophet Muhammad (sallallahu alaihi wasallam) helped her and took the luggage from the woman and carried it for her. Prophet Muhammad (sallallahu alaihi wasallam) asked the woman where she was going and why? She said that I am leaving this town as I have heard that a magician named Muhammad (nauzubillah)... etc...

1. Is it true because I have heard that it's not mentioned in authentic hadith? Also on youtube this story is a nasheed sung by someone...nasheeds name is likha ha ek zaifa thi...

2. Is listening to it permissible or am I sinning by listening to this?

Making the condition that one can break one's oath if one is unwell

Q: I made an oath to fast for a month but stipulated in the oath that if I felt unwell, I could break it. So, about a week in I had some discomfort in my chest, and felt that I should stop, so I did. (I did not break a fast). Does this mean there's no expiation? Because I gave myself some leeway in the oath I made.

Also, is it permitted to pay a charity to fulfill the kafaarat yameen on your behalf? If you make the expiation you are forgiven for breaking the oath by Allah azza wa jal?

Was it predestined for Aadam (alaihis salaam) to eat from the tree in Jannah?

Q: Someone I know asked me a question regarding Islam, and I didn't have a substantial answer to give due to lack of knowledge. And frankly, I myself am in a delimma regarding it.

In surah al Baqarah 2:30 Allah Ta'ala told the angels that He is going to create a new being who will act as his khalifa on earth. This was prior to creation of Adam (alaihis salaam). As I understand, Adam (alaihis salaam) was predestined to be sent to earth even before he was created. However after his creation, he had to eat from the tree to be expelled from earth.

From my feeble understanding, Adam (alaihis salaam) didn't have any choice because Allah Ta'ala created Adam (alaihis salaam) with the specific purpose of functioning as His khalifa on earth.

So was Allah Ta'ala going to send Adam (alaihis salaam) to the earth regardless of his disobedience? Doesn't this also mean that Adam (alaihis salaam) predestined to disobey Allah Ta'ala?

Hadith regarding the Khawaarij

Q: Can you please explain this hadith (2nd last hadith of Bukhari): Is this talking about Qaris from Egypt like Abdul Basit? What does this hadith mean?

Narrated Abu Sa`id Al-Khudri: The Prophet (ﷺ) said, "There will emerge from the East some people who will recite the Qur'an but it will not exceed their throats and who will go out of (renounce) the religion (Islam) as an arrow passes through the game, and they will never come back to it unless the arrow, comes back to the middle of the bow (by itself) (i.e., impossible). The people asked, "What will their signs be?" He said, "Their sign will be the habit of shaving (of their beards and their heads). (Fath-ul-Bari, Page 322, Vol. 17th)
