Question:
How do we get rid of thoughts like Jannat is too good to be true?
Answer:
You need an Iman boost. The best way to do this is
a) read lots of the Quran.
B) read stories of the Sahaba.
Here are some links: http://www.islamibayanaat.com/EnglishLiterature.htm. Hayatus Sahaba is an excellent source for stories of the Sahaba. Mufti Taqi’s English Qran translation is there too. http://shaikhsohail.wordpress.com/2009/04/25/hayatus-sahaba-lives-of-the-sahabah/. It may also help you to be a in a good Islamic environment for a while, so going out in Jamaat might be good for you.
