I converted one and a half years ago and at one point I calculated my missing prayers so I could offer them. I was doing, everyday two past days prayers so I was going to finish at 2019. But then a friend of mine said I'm not obligated to do so because I converted and it's like I have no sins before that. Now another friend says that I was a neglecting muslim so I have to offer the missed prayers.
I was a deist before, I believed in a 'creator' because I couldn't explain what happend/ what was there before the planets started to cool off. So I assumed there was something that started everything. Besides that, I believed in being a 'good' person because I wanted to go to heaven. But I wasn't sure of the concept of heaven. I just assumed it was there, next to hell. One day I had a dream and I started to believe. I became aware of Allah's presence. So I don't know if I'm responsible of the missing prayers or not.
