It is narrated from Samurah bin Jundub (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "When any of you comes to a herd (to drink milk), if its owner is present among them, he should seek permission from him. If he gives permission, then drink the milk. If none of them is present, then call out three times. If someone responds, seek permission from him, and if no one responds, then drink the milk but do not take it away with you."

Imam Tirmidhi says:
1- The hadith of Samurah is Hasan Gharib.
2- In this chapter, there are also ahadith from Umar and Abu Sa'id al-Khudri.
3- The people of knowledge act upon this, Ahmad and Ishaq bin Rahwayh also hold this view.
4- Ali bin al-Madini says that the hearing of Hasan from Samurah is established.
5- Some hadith scholars have criticized the narration of Hasan which he narrated from Samurah; they say that Hasan used to narrate hadith from the written record (sahifah) of Samurah.
