Subhanallah, I was reading Surat Al-qasas when I came across this sentence in verse 32 When Allah, exhaled is He, is talking to prophet Moses, peace be upon him and He tells him:
.1 And cross your arms tightly to calm your fears.

Watch this video of Peter levine where he explain in minute 2:45 of the video a technique to calm one’s fear in what is considered to be new techniques to work with trauma patients.

It turns out it’s an old technique written hundreds of years ago in the Qur’an 😉
