Assalam alaykum.

I have a question concerning Islam and I don’t know where else to write. I would be really grateful for any answer. I'm wondering why several ayat start with, "We," for example, "If We had sent unto thee a written (message)...." and "We know indeed the grief which their words do cause thee...." and many more. I am just wondering if there could be a message behind it.

Thank you in advance!
