"The Prophet hurried through Wadi Muhassir." Bishr (one of the narrators) added: "He departed from Jam calmly and he ordered them (the people) to be calm." And Abu Nu'aim (one of the narrators) added: "And he ordered them to do the stoning with what was similar to pebbles for Al-Khadhf' And he said: "Perhaps I will not see you after this year."
Jami` at-Tirmidhi Book 9, Hadith 79
