RIYA DESTROY REWARD

Syidad bin Ausi said, "One day I saw the Prophet Muhammad was crying, then I asked him, O Messenger of Allah, why are you crying?"
Word of the Prophet Muhammad, "Yes Syidad, I cried because my people will be concerned to shirk, know that they did not worship idols but they apply riya 'with the deeds to their deeds."
Prophet said again, "The guardian angels will rise to bring charitable deeds of the servants of his fasting, his prayer, his charity and so on. The angel has a voice like the sound of bees and have a sun 3000 and together they were angels and they took to the sky seventh. "

The angel assigned to the sky and said to his guardian angel, "Stand ye all of this and Tap your charitable deeds to face the owner and all members and close his heart, I really hinder the arrival of my God every charitable act that is not desired to God other than Allah (to make something charitable not for God). "
"Applicable riya 'fiqh among experts is that the desired height so that they become the title. Among the scholars also to become popular in cities and among the public. Allah SWT has ordered me not to let my past deeds will come in addition to me."

Guardian angels bring charitable pious people and then carried by the angels in heaven, so open all the protective cover and up to Allah SWT They stopped in front of God and gives testimony to the charity of those who truly pious and sincere for Allah.
Then Allah says that meant, "You all are angels Hafazdah (guardian angels) on deeds, deeds of my servant, while I was the one who watched and knew his heart, that he really wants this charity is not for me, curse the angels and the curse of all things in heaven. "
