Abu Dawud Book 27, Hadith Number 4059.

Narated By Rafi’ ibn Khadij : We went out with the Apostle of Allah (PBUH) on a journey, and we had on our saddles and camels garments consisting of red warp of wool. The Apostle of Allah (PBUH) said: Do I not see that red colour has dominated you. We then got up quickly on account of this saying of the Apostle of Allah (PBUH) and some of our camels ran away. We then took the garments and withdrew them.
