It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "When Jibreel (peace be upon him) took Ibrahim (peace be upon him) towards Jamrah Aqabah, Satan appeared before them on the way. Ibrahim (peace be upon him) threw seven pebbles at him and he went away. Near Jamrah Wusta, he appeared again, so Ibrahim (peace be upon him) again threw seven pebbles at him. This is the place where Ibrahim (peace be upon him) laid Ismail (peace be upon him) down on his forehead. The same happened near Jamrah Akhirah. When Ibrahim (peace be upon him) intended to sacrifice his son Ishaq (according to the correct opinion, Ismail), he said: 'Father! Tie me up so that I cannot move, lest your clothes be stained with my blood.' So he did so, and when he took the knife to slaughter him, a voice called out from behind: 'O Ibrahim! You have fulfilled your dream.'"
