Brothers and sisters the definition of the word character is the mental and moral qualities distinctive to an individual.
ur mental qualities are created on the environment u grow into. we learn left and right, we are taught to eat in the right hand if we choose to eat on the left does that mean god made us that way? not it does not
like the previous repliers all said we all know right from wrong but we just choose our path.
of course if a child grows in an environment where stealing is ok , then he's obviously going to think that its the right think to do. but as he grows so does he's understanding, the choices remains his. God did not teach him that it was ok to steal but the people he grew up with did.
ALLAH guides whomever he wills and remain misguided whomever he wills.
then again u need to look at our lives ALLAH constantly tries to guide us all.
every-time a sister looks at a hijab that she has at home and chooses to go out without it, it is a guidance she is rejecting. everytime someone tells to pray and u do not pray, its a guidance you have rejected.
like the brother said everyone knows about ISLAM, the fact that it is so proves that ALLAH SWT is guiding us all, but most refuse the guidance. u make the first step ALLAH SWT will then make u run.
from personal experiences, when i started to wear the hijab coz my friend told me to wear it with her, then i wanted to keep it coz of ALLAH SWT. ALLAH SWT then made it so that i could go out without it, it became part of me.
if ALLAH SWT made u bad. then u will not have the opportunity to do anything good. but as u can see we all have that ability, which means that our character depends on what we accept in life and what moral we choose to follow. otherwise a murderer action is justified.
