Sayyidah Aishah Siddiqah (may Allah be pleased with her) relates: I heard the Prophet (peace and blessings be upon him), while he was delivering a sermon to the people, say: "Your place will be in Paradise." The narrator says: That is, whoever guards that which is between his two jaws, namely the tongue, and that which is between his two legs, namely the private parts (his abode will be Paradise).
Abu Ya'la recorded it, and its narrators are the narrators of the Sahih.
