Sahih al-Bukhari Book 65, Hadith 242
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)
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."
While I was in the company of the Prophet (ﷺ) on a farm and he was reclining on a palm leave stalk, some Jews passed by. Some of them said to the others. "Ask him (the Prophet (ﷺ) about the spirit." Some of them said, "What urges you to ask him about it" Others said, "(Don't) lest he should give you a reply which you dislike." But they said, "Ask him." So they asked him about the Spirit. The Prophet (ﷺ) kept quiet and did not give them any answer. I knew that he was being divinely inspired so I stayed at my place. When the divine inspiration had been revealed, the Prophet (ﷺ) said. "They ask you (O, Muhammad) concerning the Spirit, Say: "The spirit," its knowledge is with my Lord; and of knowledge you (mankind) have been given only a Little." (17.85)
