It is narrated from Ubadah bin Nusayy: I passed by some people who had gathered around an elderly man who was narrating hadith. They made way for me, and I saw that the elderly man was saying: "O people! Three things are a trust with you; whoever safeguards them is a believer, and whoever does not safeguard them is not a believer: (namely) if he says that he has prayed when he has not prayed, or says that he has fasted when he has not fasted, or that he has taken the ritual bath (ghusl) for major impurity when he has not." Ubadah says: I asked the person sitting beside me: "Who is this?" He said: "This is Sayyiduna Uqbah bin Amir al-Juhani (may Allah be pleased with him), the Companion of the Messenger of Allah (peace and blessings be upon him)."
