Sayyiduna Dirar bin al-Azwar (may Allah be pleased with him) narrates: We gave the Prophet (peace and blessings be upon him) a milch she-camel as a gift. The narrator says: I began milking her, and when I began to strain her, the Prophet (peace and blessings be upon him) said: "Do not do that! Leave the caller of the milk."
Imam Ahmad and al-Tabarani recorded it; they say: "Leave the callers of the milk, and leave some for me."
They recorded it with several chains; the narrators of one of the chains are thiqat (trustworthy).
