Hmm thats a good question
To some extent, praying 5x a day could be more important, I'll admit I dont do that though
But then some people see it pray x5 a day, drink alcohol, dont fast, and eat pork- so whats the point praying?
I think they are all sins in their own right, and we should avoid them all, but some are more severe than others. They are as bad as each other and it depends how YOU define a bad muslim.
I think the key to being a good muslim is being a decent person and having prematial relationships, clubbing not dressed modestly doesn't make you decent...
also, being a good citizen i.e not causing trouble, bullying etc is a crucial thing in Islam especially charity. I am so grateful that Islam encourages charity and being content with what we have.
Plus, if you're wearing the hijaab as you've been forced, or for the wrong reasons (i.e fashion statement, to show you are religious) then you won't get the good deed as if you are wearing because you want to if that makes sense, and its better to come out of yoru own shell and wear it when you feel ready otherwise you're abusing it.
If you drink, eat pork, club etc but pray for the right reasons its the same as not eating pork,drinking, or clubbing and not praying 5x a day.
I'm almost certain everyone comits some sort of sin...its just bad when you cover it up or deny it...like you admit to drinking and admit its a sin, same as I try to admit I dont wear a hijaab but acknowledge its a sin, whereas some try to find excuses for themselves.
Apparently, if you don't pray 5x a day your husband is suppose to beat you (if you're a woman)...literally fml as I'll be getting beats for the rest of my life...
