The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)

Dawud :: Book 10 : Hadith 1790

Narrated Mu'awiyah ibn AbuSufyan:

Mu'awiyah said to the Companions of the Prophet (peace_be_upon_him): Do you know that the Apostle of Allah (peace_be_upon_him) prohibited from doing so and so (and he prohibited from) riding on the skins of leopards? They said: Yes.

He again said: You know that he prohibited combining hajj and umrah. They replied: This we do not (know). He said: This was prohibited along with other things, but you forgot.
