Ya'la b. Murra ath-Thaqafi said:There are three things I saw relating to God's messenger. While we were travelling with him, we passed a camel being used for irrigation, and when the camel saw him, it rumbled and bent down its neck. The Prophet stopped beside it and asked where the owner of that camel was, and when he came, he asked him to sell it to him. He replied, "No, I shall not give it to you, messenger of God, it belongs to a family which has no other means of livelihood." He said, "Since you have mentioned this about it, note that it has complained to me of a great amount of work and a small amount of fodder; so, treat it well [*] ." We then travelled on, and when we came to a stage and the Prophet had lain down to sleep a tree came cleaving the earth till it overshadowed him and then returned to its place. When God's messenger awoke, I mentioned the m atter to him and he said, "It is a tree which asked its Lord's permission to give a salutation to God's messenger, and He allowed it." We then travelled on, and when we passed a watering-place a woman brought a son of hers who was possessed, and the Prophet seized his nostril and said, "Come out, for I am Muhammad, God's messenger." We then travelled on, and when we passed that watering-place on the way back he asked the woman about the boy and she said, "I swear by Him who commissioned you with the truth that we have seen nothing in him to disturb us since you left." *The Prophet evidently had no desire to take the camel either by payment or as a gift, since it was the man's only means of earning a livelihood. He therefore left him with an exhortation to treat the camel properly. It is transmitted in Sharh as-sunna.
