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."
Amr bin Murrah (may Allah have mercy on him) says that a person narrated a hadith to us in the house of Abu Ubaidah, that he heard Abdullah bin Amr (may Allah be pleased with them both) narrate a hadith from Abdullah bin Umar (may Allah be pleased with them both), who said that the Messenger of Allah (peace and blessings be upon him) said, and... he narrated this hadith, but it did not contain the words «يوم القيامة» (on the Day of Resurrection).
