Sayyiduna Abu Musa (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever guards that which is between his two jaws (that is, the tongue) and his private parts will enter Paradise."
Ahmad recorded it, and Abu Ya'la and al-Tabarani recorded something similar. The narrators of al-Tabarani and Abu Ya'la are thiqat (trustworthy). Among the narrators of Ahmad there is a narrator who is not named, and the rest of its narrators are thiqat (trustworthy). It appears that the narrator whom Ahmad did not name is Sulayman bin Yasar.
