Sayyiduna Samurah bin Jundub (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) used to command hospitality (to guests), but he would forbid milking a man's animal without his permission. He (peace and blessings be upon him) would say: "Their milk is just like what is in your bags." Or he said some word similar to it.
Imam Bazzar and Imam Tabarani recorded it in al-Mu'jam al-Kabir, and he narrated these words: "Just like what is in your bags; neither of them is more lawful than the other." The chain of Imam Tabarani contains a mastur (one of unknown status) narrator, and the chain of Imam Tabarani is da'if (weak).
