Sins

why there must be a sin? if Allah SWT promised heaven for the believer?

...

i stood pensive looking at the notes a friend who wrote it thereby complicated

and i nodded agree with writing that is in the record of my friend

and a few weeks after that, i bought some books with titled

"i got close you are near" by Yadi Saeful Hidayat

i find the answer!

"and (by) the soul and He who proportioned it. 

and inspired it (with discernment of) it's wickedness and it's righteousness

He has succeeded who purifies it,

and he has failed who instills it (with corruption)"

Ash-Shams (91): 7-10

everything was on our grasp

you can be good or you can be bad

sin is come from the lust that you can't control it and  can't manage it. example

if you can control your meal maybe you can lose your weight, right?

if you can manage your money maybe you can save your money

control and manage

that's why, there is patient and sincere

so we can be grateful to what Allah SWT gave to us

and if there is no lust maybe we can be like angel

no eat

no love

no children

no education

no science

no technology

everything was flat
