The Messenger of Allah ﷺ sent ahead some boys from Banu AbdulMuttalib on donkeys on the night of al-Muzdalifah. He began to pat our thighs (out of love) and said: O young! boys do not throw pebbles at the jamrah till the sun rises. Abu Dawud said: The Arabic word al-lath means to strike softly.
قَدَّمَنَا رَسُولُ اللَّهِ ﷺ لَيْلَةَ الْمُزْدَلِفَةِ أُغَيْلِمَةَ بَنِي عَبْدِ الْمُطَّلِبِ عَلَى حُمُرَاتٍ فَجَعَلَ يَلْطَحُ أَفْخَاذَنَا وَيَقُولُ أُبَيْنِيَّ لاَ تَرْمُوا الْجَمْرَةَ حَتَّى تَطْلُعَ الشَّمْسُ
