Sahih al-Bukhari Book 65, Hadith 241
Allah's Messenger (ﷺ) said, "Whoever, after listening to the Adhan (for the prayer) says, 'O Allah, the Lord
of this complete call and of this prayer, which is going to be established! Give Muhammad Al-Wasila
and Al-Fadila and raise him to Al-Maqam-al-Mahmud which You have promised him,' will be granted
my intercession for him on the Day of Resurrection."
On the Day of Resurrection the people will fall on their knees and every nation will follow their prophet and they will say, "O so-and-so! Intercede (for us with Allah), "till (the right) intercession is given to the Prophet (Muhammad) and that will be the day when Allah will raise him into a station of praise and glory (i.e. Al-Maqam -al-Mahmud).
Allah's Messenger (ﷺ) 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)
