Narrated Ibn `Umar: The Prophet said, "While a man was walking, dragging his dress with pride, he was caused to be swallowed by the earth and will go on sinking in it till the Day of Resurrection."

Narrated Abu Huraira: The Prophet said, "We are the last (to come) but we will be the foremost on the Day of Resurrection, nations were given the Book (i.e. Scripture) before us, and we were given the Holy Book after them. This (i.e. Friday) is the day about which they differed. So the next day (i.e. Saturday) was prescribed for the Jews and the day after it (i.e. Sunday) for the Christians.

It is incumbent on every Muslim to wash his head and body on a Day (i.e. Friday) (at least) in every seven days."

Narrated Sa`id bin Al-Musaiyab: When Muawiya bin Abu Sufyan came to Medina for the last time, he delivered a sermon before us. He took out a tuft of hair and said, "I never thought that someone other than the Jews would do such a thing (i.e. use false hair). The Prophet named such a practice, 'Az-Zur' (i.e. falsehood)," meaning the use of false hair.
