Just search Satan stays on the nose of Muslims...
It is in the hadith I think...you mean it is not credible?

We don’t find in Quran or Hadith 

We wash not only nose, also mouth, ear, Hand,face,feet.

O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles." - (Al-Ma’idah: 6)
