A man who looked like a Muslim passed by Sayyiduna Uqbah bin Amir al-Juhani (may Allah be pleased with him) and greeted Sayyiduna Uqbah bin Amir (may Allah be pleased with him). He returned the greeting, adding: "And the mercy of Allah and His blessings." Then his servant asked: "Do you know whom you have returned the greeting to?" He said: "Is he not a Muslim man?" He said: "No, rather he is a Christian."
