Amr bin Murrah, may Allah have mercy on him, says that we were sitting with Abu Ubaidah when people started discussing ostentation. An elder whose kunya was Abu Yazid said: I heard Sayyiduna Abdullah bin Amr, may Allah be pleased with them both, say that I heard the Messenger of Allah, peace and blessings be upon him, say: "Whoever shows his deeds to people, Allah will make that deed reach the ears of His creation on the Day of Resurrection and will humiliate and disgrace him."
