(5) باب صفة الحج ودخول مكة
Ibn 'Umar (RAA) narrated that he used to throw the pebbles of al-Jamrat ud-Duniya (the Jamrah near to the Khaif mosque) with seven small pebbles, and would recite Takbir when throwing each pebble. Then he would go ahead until he reached the bottom of the valley, where he would stand for quite a long time facing the direction of the Qiblah, and raising his hands, while supplicating Allah. Then he went and threw seven pebbles at the second Jamrah(al-Jamarah al·Wosta) while saying Allahu Akbar with each throw. He would then turn to the left of the bottom of the valley, stand there facing the Qiblah and supplicating to Allah with his hands raised. Then he went to Jamrat-ul Aqabah, threw seven pebbles at it, uttering the Takbir with each throw. After that he left and did not pause. He would then say, 'I saw the Prophet (ﷺ) doing like this.'
