Karma.?
No.
In Islam we have Kaffarah.
What you give,
You will get it back
Either it is in a good way or vice versa.
Allah is fair,
You know.?

Whoever hurt you just be patient and let Kaffarah bite them.

Assalamu alaikum,
I had decided I will post 10 quotes everyday
in shaa Allah.

Pray for me.

That whatever I am asking Allah for
He bless me with it.
