What teachings did the Prophet Muhammad (peace be upon him) give when he entered Mecca (in the year of the Conquest) and saw three-hundred and sixty idols around the Ka`ba?
 Narrated `Abdullah bin Masud:                     Allah's Apostle entered Mecca (in the year of the Conquest) and there were three-hundred and sixty idols around the Ka`ba. He then started hitting them with a stick in his hand and say: 'Truth (i.e. Islam) has come and falsehood (disbelief) vanished. Truly falsehood (disbelief) is ever bound to vanish.' (17.81) 'Truth has come and falsehood (Iblis) can not create anything.' (34.49)
