Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "Whoever does a good deed to make people hear of it, Allah will disgrace him on the Day of Resurrection; and whoever shows off, Allah will disgrace him on the Day of Resurrection; and whoever humbles himself for the sake of Allah out of humility, Allah will raise him on the Day of Resurrection."
