Salam I pray 5 times a day alhamdulilah but only the fard salah. The problem that I'm having is I feel no real connection which makes me so guilty. I want to be able to feel close to Allah but I fear my imaan is low and there are days when I don't even feel like praying. Is it a sin that I'm feeling this way?
Alaikumassalam wa rahmatullah,
If you do not feel close to God, that is a sign that you are not spending enough time in His presence. I strongly recommend praying tahajjud (see here for details) to everyone who wishes to feel closer to God. It is impossible to continue feeling close to God if you do not work for it daily.
Islam does not hold you responsible for how you feel, but for what you do. God does not ask you to do more than you are capable. So it is up to you to decide whether you are neglecting your duties toward Him or whether this is the most you can do.
Best wishes.
