The Messenger of Allah ﷺ hastened from al-Muzdalifah with a quite demeanour and ordered them (the people) to throw small pebbles and he hastened in the valley (wadi) of Muhassir. (Using translation from Abū Dāʾūd 1944)
أَمَرَهُمْ رَسُولُ اللَّهِ ﷺ فَرَمَوْا بِمِثْلِ حَصَى الْخَذْفِ وَأَوْضَعَ فِي وَادِي مُحَسِّرٍ وَقَالَ «عَلَيْكُمُ السَّكِينَةَ»
