Musannaf Ibn Abi Shayba 28:1139

Waki’ narrated to us, he said: Isma’il bin Abi Khalid narrated to us, from Qays, who said: The Prophet, may Allah bless him and grant him peace, sent ‘Amr bin al-‘As on the expedition of Dhat al-Salasil. A severe cold afflicted them, so he said: "Let no man kindle a fire." Then he fought the people. When they came to the Prophet, may Allah bless him and grant him peace, they complained about that to him. He [‘Amr] said: "O Messenger of Allah, there was a scarcity among my companions, and I feared that the people would see their scarcity, and I forbade them from pursuing the enemy for fear that they might have an ambush behind the mountain." He said: The Messenger of Allah, may Allah bless him and grant him peace, was pleased with that.
