It is desirable to stand facing the Qiblah, to praise Allah, while supplicating to Him for forgiveness for oneself, and for other fellow Muslims. Ahmad and Bukhari have reported from Salim bin Abdullah bin ‘Umar and he from his father that when the Prophet (peace be upon him) threw pebbles at the first Jamarah, which is near the mosque, he said, Allahu Akbar. Thus he threw seven pebbles and each time he said Allahu Akbar. Then he went, turned left toward the bottom of the valley. There he stood tor quite a long time facing the direction of Qiblah, and raising his hands supplicated to Allah. Then he went and threw seven pebbles at the second Jamarah saying Allahu Akbar with each throw. Thereafter he went to the left of the bottom of the valley, stood there facing Qiblah and supplicated to Allah with raised hands. Then he went to the Jamarah near Aqabah, threw seven pebbles at it, uttering a fakhir with each throw. After this he left and did not pause. According to this hadith the Prophet (peace be upon him) did not pause after throwing pebbles at the Jamarah Al-Aqabah, but he did pause after throwing pebbles at the other two Jamarahs.
The scholars have in the light of the above hadith suggested that after any throwing (of pebbles at the Jamarahs) that is not followed by another throwing the same day one should not stop (for supplications), but if one throwing (of pebbles) is followed by another throwing the same day one should stand there for supplications.
Ibn Majah has reported from Ibn ‘Abbas that after throwing pebbles at the Jamarah al-Aqabah, the Prophet (peace be upon him) used to leave, and not stop (for supplications).
