Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: Where did the Prophet (saws) fix the flag on the day of the conquest of Makkah?
Narrated Ibn `Abbas:
When Allah's Messenger (ﷺ) arrived in Mecca, he refused to enter the Ka`ba while there were idols in it. So he ordered that they be taken out. The pictures of the (Prophets) Abraham and Ishmael, holding arrows of divination in their hands, were carried out. The Prophet (ﷺ) said, "May Allah ruin them (i.e. the infidels) for they knew very well that they (i.e. Abraham and Ishmael) never drew lots by these (divination arrows). Then the Prophet (ﷺ) entered the Ka`ba and said. "Allahu Akbar" in all its directions and came out and not offer any prayer therein.
