A man greeting another each time he meets him

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."

Mujahid said: Two men from the Companions of the Prophet (peace and blessings be upon him) would be travelling together when a tree would separate them, and when they met again, one of them would greet the other.

Amr bin Murrah said: Abu al-Bakhtari and Sa'id bin Jubayr both suffered from stomach trouble. They would come back and greet one another again.

Al-A'mash said: Ibrahim would not part from me except with a salam. I would come and then go, and he would greet me; then I would come and then go, and he would greet me.

Al-Awwam said that Ibrahim al-Taymi said: A man among them would part from his companion with nothing but a tree coming between them, then he would meet him and greet him.
