Hadees related to dishevelled

Anas Radiyallahu 'anhu narrates: I heard Rasulullah Sallallahu 'alaihi wasallam saying: Many a dishevelled one, covered in dust, clothed in old sheets, turned away from peoples doors, (has such a attachment with Allah that) if he swears by Allah, certainly Allah will fulfill his words. (Tabarani, Majma-'uz-Zawaid)

Note: This hadlth implies that one must not look down upon a dishevelled and dust laden person, as many-a-such are special slaves of Allah. However, it does not mean such an appearance is to be encouraged. (Ma'ariful Hadith)
