The description of tayammum is summarized by the Muslim intending to do tayammum, saying: “In the name of God,” then he hits the ground with his palms, then blows them; To reduce dust from them, he wipes his face with his hands, then wipes his palms, and it is permissible to wipe the hands before wiping the face.

So each of them worked hard to realize the prayer, so Omar - may God be pleased with him - did not pray. Like the description of washing in the necessity of circulating the body with dirt, so he mentioned to the Messenger of God - may God bless him and grant him peace - what happened with them; He answered them - with the aforementioned hadeeth -.
