Sayyiduna Jabir (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "Do not give permission (to enter) to one who does not first greet with salam."
(Allamah al-Haythami says:) I say: Tirmidhi has recorded a hadith from this Companion, but not in this wording.
Abu Ya'la recorded it, and its chain contains a narrator whom I do not know.
