Praise the presence of the Almighty God for all the abundance of Rahmat, Taufik and his father so that we can complete the preparation of the digital hadith application about peace and its very simple contents. Hopefully this application can be used as one of the references, instructions and guidelines for readers in developing education in their lives.

On this occasion we would like to express our deepest gratitude to:
1. Campus Holy IAIN Faculty of Islamic Law and Islamic Thought
2. Hadith Study Center, Cinagara Bogor
3. Mother of the field supervisor lecturer
4. Our parents who have helped both morally and materially
5. Colleagues of the Holy IAIN group who have collaborated in the preparation of this application.

We realize that the preparation of this application is far from perfect, both in terms of preparation, discussion, and writing. Therefore, we hope the readers to provide constructive inputs to the perfection of this application.
We hope that this application can help increase knowledge and experience for readers, so that we can improve the form and content of this application so that in the future it can be better.
This application is still far from lacking because the experience we have is very minimal. Therefore, we expect the readers to provide constructive inputs to the perfection of this application.
