From Sahih Muslim (Hadith 4507):
Shu'ba reported:Salama b. Kuhail informed me or he informed people and I was among them. He said: I heard Sawaid b. Ghafala who reported: I went out along with Zaid b. Suhan and Salman b. Rabi'a, and found a whip, the rest of the hadith is the same up to the words:" I made use of that." Shu'ba said: I heard him say after ten years, that he made an announcement of it for one year
