Musannaf Ibn Abi Shaybah 27370 — A man greeting another each time he

Nafi' said: I was travelling with Abdullah bin Abi Zakariyya in the land of the Romans when my riding animal needed to urinate, so the animal stood and urinated. Then I caught up with him again. He said: "Why did you not give salam?" I said: "I only just parted from you." He said: "Even if you only just parted from me. The Companions of the Messenger of Allah (peace and blessings be upon him) would be travelling when trees would separate them, and when they came together again they would greet one another."
