Aqaaid

Q: I am reverted to Islam and used to be a Hindu. I do not worship idols but during some days Hindu people worship the dead people of their family to show them respect and for that they burn something like coal in name of them and prostate in front of them. I am secretly following Islam and my mother told me to prostrate in front of that even though I was a Muslim, I just sat down and took my head down. I did not touch the ground with my nose and head and was taking name of Allah. I cannot say no to my parents. Have I done shirk? I even cried after this in front of Allah and I am now feeling that I do not deserve to be a servant of Allah. What can I do now? 

Q: I was passing by the road and on a car's mirror it was written God forbid "Jesus is the lord" god forbid. I said to my self that there is no lord. But I didn't mean to say it to Allah. I have belief in Allah. Now what I said did it made me sinful? 

Q: Please give me the ruling regarding the following: 

Question: In order to convince someone of something, someone said, for example, "So-and-so does not have a car. May I be a disbeliever if he has!" Is it considered to be an oath?

Answer: There are two rulings on this issue:

1. If one says, "So-and-so does not have a car. May I be a disbeliever if he has," the relevant person becomes a disbeliever whether that person has a car or not. One's intention does not count. That is, it is not valid.

2. If one utters something that causes disbelief with the intention of taking an oath, he is considered to have taken an oath. However, such an oath is not a Muslim's oath.

Q: I would like to know about Nawaqid al Islam by Muhammed ibn Abdul Wahhab. I have asked around at bookstores asking about it but no one has heard of it. I read it is about shirk and nullifiers so I would of like to read it but I cant understand if it is reputable to read? Is it something that is debatable? Can you please shed some light on the above mentioned book?

Q: I have a serious problem of blasphemous abusive words that comes frequently for Allah. Now I am just ignoring it but before I didnt know how to deal with them. A few years back, I used to correct those thoughts and repeat within my mind, by saying that Allah is great. And then I used to say blasphemy words to shaitan that you are this..... (bad and vulgar words). Sometime ago I was talking to my relative, and all of a sudden when I was correcting her I spoke those bad words for Allah. Since then I am very upset and have feeling remorse. Sometimes this thought comes that I am actually thinking these words on purpose.

Q: I was reading a book named "Diwaan e Shafi'i". Kindly guide me about its authenticity.

Should one read it and believe that all this book contains are authentic poems of one of four jurisprudents of Ahlas Sunnah (Imam Muhammad Ibn Idrīs al Shafiʿi)?

Q: I know that if a Muslim helps a non Muslim against Muslims, he leaves the fold of Islam. What is the crieteria of help? For example if I have a non Muslim friend and I talk to her about a Muslim which may lead to physical or mental harm or loss of rights to the said Muslim, will that be kufr too? I used to daily think that this applied in case of war/weaponry only.
