Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Trim these and leave this." What the Prophet (peace and blessings be upon him) meant was: trim the part below the lower lip and leave the beard.
(Allamah al-Haythami says:) I say:
This narration is mentioned in the Sahih, but it does not contain the command to trim the part below the lower lip.
Al-Tabarani recorded it. Its chain contains a narrator, Thuwayr bin Abi Fakhitah, who is matruk (abandoned).
