Question Summary:
I saw some writings on my window. What should I do?

Question Detail:

 
I am a a female of 30 years old and I live with my family in Dhaka Bangladesh. Yesterday something very weird has happened. I live on the 6th floor of an apartment and that is the top floor. In the evening i noticed a small writing in my bathroom window glass. First I was very shocked as the writing had been done from outside. there was no way someone could write it from outside as its the 6th floor and no can reach there. i called my parents and they saw it too. i tried opening the window to see if my hand reaches there but it does not go easily. and if someone has to write something it would be impossible for them to write it like that on the outside of the glass.
 
we hot very scared. because i thought what if someone was trying to do something bad to us. but then i realized its Arabic words but by the time I could take a picture of it by dad already wiped it off. but i clearly remember the writing. and i wrote it on the paper after that. I am sending you the image of it. please can u tell me what it is.
 
I am sending the picture . 1. how it looked from the inside of the bathroom window. and i don't know how it looked from the outside because no one can reach there. maybe you can guess seeing the image how it would look from the outside. but the picture I am sending is how it looked from inside. I tried to write the exact thing on paper and took a picture.
And when we tried ti wipe it off it seemed it was written with white chalk. it was weird how you could write with chalk on glass.
 
Iam trying to upload the picture but not possible here. can u give me an email id so that i can send it to you???

Sister-In-Islam,
We did not receive the picture in reference. However, you are simply facing delusions in which there is nothing to worry about. Simply ignore the incident at hand. It could have merely been bird droppings or some bird rubbing against your window.
